;
; General settings, like port number to bind to, and
; an option address (the default is to bind to all
; local addresses).

;
; Set iaxcompat to yes if you plan to use layered switches or
; some other scenario which may cause some delay when doing a
; lookup in the dialplan. It incurs a small performance hit to
; enable it. This option causes Asterisk to spawn a separate thread
; when it receives an IAX DPREQ (Dialplan Request) instead of
; blocking while it waits for a response.
;
;iaxcompat=yes
;
; Disable UDP checksums (if nochecksums is set, then no checkums will
; be calculated/checked on systems supporting this feature)
;
;nochecksums=no
;
;
; For increased security against brute force password attacks
; enable "delayreject" which will delay the sending of authentication
; reject for REGREQ or AUTHREP if there is a password.  
;
;delayreject=yes
;
; You may specify a global default AMA flag for iaxtel calls.  It must be
; one of 'default', 'omit', 'billing', or 'documentation'.  These flags
; are used in the generation of call detail records.
;
;amaflags=default
;
; ADSI (Analog Display Services Interface) can be enabled if you have
; (or may have) ADSI compatible CPE equipment
;
;adsi=no
;
; Perform an SRV lookup on outbound calls
;
;srvlookup=yes
;
; You may specify a default account for Call Detail Records in addition
; to specifying on a per-user basis
;
;accountcode=lss0101
;
; You may specify a global default language for users. 
; Can be specified also on a per-user basis
; If omitted, will fallback to english
;
;language=en
;
; This option specifies a preference for which music on hold class this channel
; should listen to when put on hold if the music class has not been set on the
; channel with Set(CHANNEL(musicclass)=whatever) in the dialplan, and the peer
; channel putting this one on hold did not suggest a music class.
;
; If this option is set to "passthrough", then the hold message will always be
; passed through as signalling instead of generating hold music locally.
;
; This option may be specified globally, or on a per-user or per-peer basis.
;
;mohinterpret=default
;
; This option specifies which music on hold class to suggest to the peer channel
; when this channel places the peer on hold. It may be specified globally or on
; a per-user or per-peer basis.
;
;mohsuggest=default
;
; Specify bandwidth of low, medium, or high to control which codecs are used
; in general.
;
bandwidth=low
;
; You can also fine tune codecs here using "allow" and "disallow" clauses
; with specific codecs.  Use "all" to represent all formats.
;
;allow=all                      ; same as bandwidth=high
;disallow=g723.1                ; Hm...  Proprietary, don't use it...
disallow=lpc10                  ; Icky sound quality...  Mr. Roboto.
;allow=gsm                      ; Always allow GSM, it's cool :)
;

; You can adjust several parameters relating to the jitter buffer.
; The jitter buffer's function is to compensate for varying
; network delay.
;
; All the jitter buffer settings are in milliseconds.
; The jitter buffer works for INCOMING audio - the outbound audio
; will be dejittered by the jitter buffer at the other end.
;
; jitterbuffer=yes|no: global default as to whether you want
; the jitter buffer at all.
;
; forcejitterbuffer=yes|no: in the ideal world, when we bridge VoIP channels
; we don't want to do jitterbuffering on the switch, since the endpoints
; can each handle this.  However, some endpoints may have poor jitterbuffers 
; themselves, so this option will force * to always jitterbuffer, even in this
; case.
;
; maxjitterbuffer: a maximum size for the jitter buffer.
; Setting a reasonable maximum here will prevent the call delay
; from rising to silly values in extreme situations; you'll hear
; SOMETHING, even though it will be jittery.
;
; resyncthreshold: when the jitterbuffer notices a significant change in delay
; that continues over a few frames, it will resync, assuming that the change in
; delay was caused by a timestamping mix-up. The threshold for noticing a
; change in delay is measured as twice the measured jitter plus this resync
; threshold.
; Resyncing can be disabled by setting this parameter to -1.
;
; maxjitterinterps: the maximum number of interpolation frames the jitterbuffer
; should return in a row. Since some clients do not send CNG/DTX frames to
; indicate silence, the jitterbuffer will assume silence has begun after
; returning this many interpolations. This prevents interpolating throughout
; a long silence.
;
;
; jittertargetextra: number of milliseconds by which the new jitter buffer
; will pad its size. the default is 40, so without modification, the new
; jitter buffer will set its size to the jitter value plus 40 milliseconds.
; increasing this value may help if your network normally has low jitter,
; but occasionally has spikes.
;

jitterbuffer=no
forcejitterbuffer=no
;maxjitterbuffer=1000
;maxjitterinterps=10
;resyncthreshold=1000
;jittertargetextra=40

;trunkfreq=20                   ; How frequently to send trunk msgs (in ms)

; Should we send timestamps for the individual sub-frames within trunk frames?
; There is a small bandwidth use for these (less than 1kbps/call), but they
; ensure that frame timestamps get sent end-to-end properly.  If both ends of
; all your trunks go directly to TDM, _and_ your trunkfreq equals the frame
; length for your codecs, you can probably suppress these.  The receiver must
; also support this feature, although they do not also need to have it enabled.
;
; trunktimestamps=yes
;
; Minimum and maximum amounts of time that IAX peers can request as
; a registration expiration interval (in seconds).
; minregexpire = 60
; maxregexpire = 60
;
; With a large amount of traffic on IAX2 trunks, there is a risk of bad voice quality due to
; the fact that the IAX2 trunking scheme depends on the Linux system to handle fragmentation of
; UDP packets. This may not be very efficient. 
; This setting sets the maximum transmission unit for IAX2 UDP trunking.
; default is 1240 bytes. Zero disables this functionality and let's the O/S handle fragmentation.
;
; trunkmtu = 0
;
; Enable IAX2 encryption.  The default is no.
;
; encryption = yes
;
; This is a compatibility option for older versions of IAX2 that do not support
; key rotation with encryption.  This option will disable the IAX_COMMAND_RTENC message.
; default is on
;
; keyrotate=off

; This option defines the maximum size an IAX2 trunk can grow to. The default value is 128000 bytes which
; represents 40ms uncompressed linear with 200 channels. Depending on different things though
; (codec in use and channels) you may need to make this value larger.
; trunkmaxsize = 128000

; IAX helper threads

; Establishes the number of iax helper threads to handle I/O.
; iaxthreadcount = 10
; Establishes the number of extra dynamic threads that may be spawned to handle I/O
; iaxmaxthreadcount = 100
;
; We can register with another IAX server to let him know where we are
; in case we have a dynamic IP address for example
;
; Register with tormenta using username marko and password secretpass
;
;register => marko:secretpass@tormenta.linux-support.net
;
; Register joe at remote host with no password
;
;register => joe@remotehost:5656
;
; Register marko at tormenta.linux-support.net using RSA key "torkey"
;
;register => marko:[torkey]@tormenta.linux-support.net
;
; Sample Registration for iaxtel
;
; Visit http://www.iaxtel.com to register with iaxtel.  Replace "user"
; and "pass" with your username and password for iaxtel.  Incoming 
; calls arrive at the "s" extension of "default" context.
;
;register => user:pass@iaxtel.com
;
; Sample Registration for IAX + FWD
;
; To register using IAX with FWD, it must be enabled by visiting the URL
; http://www.fwdnet.net/index.php?section_id=112
;
; Note that you need an extension in you default context which matches
; your free world dialup number.  Please replace "FWDNumber" with your
; FWD number and "passwd" with your password.
;
;register => FWDNumber:passwd@iax.fwdnet.net
;
;
; You can disable authentication debugging to reduce the amount of 
; debugging traffic.
;
;authdebug=no
;
; See qos.tex or Quality of Service section of asterisk.pdf for a description of these parameters.

;
; If regcontext is specified, Asterisk will dynamically create and destroy
; a NoOp priority 1 extension for a given peer who registers or unregisters
; with us.  The actual extension is the 'regexten' parameter of the registering
; peer or its name if 'regexten' is not provided.  More than one regexten
; may be supplied if they are separated by '&'.  Patterns may be used in
; regexten.
;
;regcontext=iaxregistrations
;
; If we don't get ACK to our NEW within 2000ms, and autokill is set to yes,
; then we cancel the whole thing (that's enough time for one retransmission
; only).  This is used to keep things from stalling for a long time for a host
; that is not available, but would be ill advised for bad connections.  In
; addition to 'yes' or 'no' you can also specify a number of milliseconds.
; See 'qualify' for individual peers to turn on for just a specific peer.
;
autokill=yes
;
; codecpriority controls the codec negotiation of an inbound IAX call.
; This option is inherited to all user entities.  It can also be defined 
; in each user entity separately which will override the setting in general.
;
; The valid values are:
;
; caller   - Consider the callers preferred order ahead of the host's.
; host     - Consider the host's preferred order ahead of the caller's.
; disabled - Disable the consideration of codec preference altogether.
;            (this is the original behaviour before preferences were added)
; reqonly  - Same as disabled, only do not consider capabilities if
;            the requested format is not available the call will only
;            be accepted if the requested format is available.
;
; The default value is 'host'
;
;codecpriority=host
;
; allowfwdownload controls whether this host will serve out firmware to
; IAX clients which request it.  This has only been used for the IAXy,
; and it has been recently proven that this firmware distribution method
; can be used as a source of traffic amplification attacks.  Also, the
; IAXy firmware has not been updated for at least 18 months, so unless
; you are provisioning IAXys in a secure network, we recommend that you
; leave this option to the default, off.
;
;allowfwdownload=yes

;rtcachefriends=yes     ; Cache realtime friends by adding them to the internal list
                        ; just like friends added from the config file only on a
                        ; as-needed basis? (yes|no)

;rtupdate=yes           ; Send registry updates to database using realtime? (yes|no)
                        ; If set to yes, when a IAX2 peer registers successfully,
                        ; the ip address, the origination port, the registration period,
                        ; and the username of the peer will be set to database via realtime.
                        ; If not present, defaults to 'yes'.

;rtautoclear=yes        ; Auto-Expire friends created on the fly on the same schedule
                        ; as if it had just registered? (yes|no|<seconds>)
                        ; If set to yes, when the registration expires, the friend will
                        ; vanish from the configuration until requested again.
                        ; If set to an integer, friends expire within this number of
                        ; seconds instead of the registration interval.

;rtignoreregexpire=yes  ; When reading a peer from Realtime, if the peer's registration
                        ; has expired based on its registration interval, used the stored
                        ; address information regardless. (yes|no)

;parkinglot=edvina              ; Default parkinglot for IAX peers and users

; Further user sections may be added, specifying a context and a secret used
; for connections with that given authentication name.  Limited IP based
; access control is allowed by use of "allow" and "deny" keywords.  Multiple
; rules are permitted.  Multiple permitted contexts may be specified, in
; which case the first will be the default.  You can also override caller*ID
; so that when you receive a call you set the Caller*ID to be what you want
; instead of trusting what the remote user provides
;
; There are three authentication methods that are supported:  md5, plaintext,
; and rsa.  The least secure is "plaintext", which sends passwords cleartext
; across the net.  "md5" uses a challenge/response md5 sum arrangement, but
; still requires both ends have plain text access to the secret.  "rsa" allows
; unidirectional secret knowledge through public/private keys.  If "rsa"
; authentication is used, "inkeys" is a list of acceptable public keys on the 
; local system that can be used to authenticate the remote peer, separated by
; the ":" character.  "outkey" is a single, private key to use to authenticate
; to the other side.  Public keys are named /var/lib/asterisk/keys/<name>.pub
; while private keys are named /var/lib/asterisk/keys/<name>.key.  Private
; keys should always be 3DES encrypted.

; NOTE: All hostnames and IP addresses in this file are for example purposes
