9 ; You may specify a global default AMA flag for iaxtel calls. It must be
10 ; one of 'default', 'omit', 'billing', or 'documentation'. These flags
11 ; are used in the generation of call detail records.
15 ; You may specify a default account for Call Detail Records in addition
16 ; to specifying on a per-user basis
20 ; You can fine tune codecs here using "allow" and "disallow" clauses
21 ; with specific codecs. Use "all" to represent all formats.
24 ;allow=all ; turns on all installed codecs
25 ;disallow=g723.1 ; Hm... Proprietary, don't use it...
26 ;allow=gsm ; Always allow GSM, it's cool :)
27 ;allow=ulaw ; see doc/rtp-packetization for framing options
29 ; User-Input Mode (DTMF)
31 ; valid entries are: rfc2833, inband
35 ; Default RTP Payload to send RFC2833 DTMF on. This is used to
36 ; interoperate with broken gateways which cannot successfully
37 ; negotiate a RFC2833 payload type in the TerminalCapabilitySet.
39 ; You may also specify on either a per-peer or per-user basis below.
43 ; DISCOVER - Find the Gk address using multicast
44 ; DISABLE - Disable the use of a GK
45 ; <IP address> or <Host name> - The acutal IP address or hostname of your GK
49 ; Tell Asterisk whether or not to accept Gatekeeper
50 ; routed calls or not. Normally this should always
51 ; be set to yes, unless you want to have finer control
52 ; over which users are allowed access to Asterisk.
57 ; When the channel works without gatekeeper, there is possible to
58 ; reject calls from anonymous (not listed in users) callers.
59 ; Default is to allow anonymous calls.
61 ;AcceptAnonymous = yes
63 ; Optionally you can determine a user by Source IP versus its H.323 alias.
64 ; Default behavour is to determine user by H.323 alias.
68 ; Default context gets used in siutations where you are using
69 ; the GK routed model or no type=user was found. This gives you
70 ; the ability to either play an invalid message or to simply not
71 ; use user authentication at all.
75 ; Use this option to help Cisco (or other) gateways to setup backward voice
76 ; path to pass inband tones to calling user (see, for example,
77 ; http://www.cisco.com/warp/public/788/voip/ringback.html)
79 ; Add PROGRESS information element to SETUP message sent on outbound calls
80 ; to notify about required backward voice path. Valid values are:
81 ; 0 - don't add PROGRESS information element (default);
82 ; 1 - call is not end-end ISDN, further call progress information can
83 ; possibly be available in-band;
84 ; 3 - origination address is non-ISDN (Cisco accepts this value only);
85 ; 8 - in-band information or an appropriate pattern is now available;
88 ; Add PROGRESS information element (IE) to ALERT message sent on incoming
89 ; calls to notify about required backwared voice path. Valid values are:
90 ; 0 - don't add PROGRESS IE (default);
91 ; 8 - in-band information or an appropriate pattern is now available;
94 ; Generate PROGRESS message when H.323 audio path has established to create
95 ; backward audio path at other end of a call.
98 ; Specify how to inject non-standard information into H.323 messages. When
99 ; the channel receives messages with tunneled information, it automatically
100 ; enables the same option for all further outgoing messages independedly on
101 ; options has been set by the configuration. This behavior is required, for
102 ; example, for Cisco CallManager when Q.SIG tunneling is enabled for a
103 ; gateway where Asterisk lives.
104 ; The option can be used multiple times, one option per line.
105 ;tunneling=none ; Totally disable tunneling (default)
106 ;tunneling=cisco ; Enable Cisco-specific tunneling
107 ;tunneling=qsig ; Enable tunneling via Q.SIG messages
109 ;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
110 ; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of a
111 ; H323 channel. Defaults to "no". An enabled jitterbuffer will
112 ; be used only if the sending side can create and the receiving
113 ; side can not accept jitter. The H323 channel can accept jitter,
114 ; thus an enabled jitterbuffer on the receive H323 side will only
115 ; be used if the sending side can create jitter and jbforce is
118 ; jbforce = no ; Forces the use of a jitterbuffer on the receive side of a H323
119 ; channel. Defaults to "no".
121 ; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
123 ; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
124 ; resynchronized. Useful to improve the quality of the voice, with
125 ; big jumps in/broken timestamps, usualy sent from exotic devices
126 ; and programs. Defaults to 1000.
128 ; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of a H323
129 ; channel. Two implementations are currenlty available - "fixed"
130 ; (with size always equals to jbmax-size) and "adaptive" (with
131 ; variable size, actually the new jb of IAX2). Defaults to fixed.
133 ; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".
134 ;-----------------------------------------------------------------------------------
136 ; H.323 Alias definitions
138 ; Type 'h323' will register aliases to the endpoint
139 ; and Gatekeeper, if there is one.
141 ; Example: if someone calls time@your.asterisk.box.com
142 ; Asterisk will send the call to the extension 'time'
143 ; in the context default
146 ; exten => time,1,Answer
147 ; exten => time,2,Playback,current-time
149 ; Keyword's 'prefix' and 'e164' are only make sense when
150 ; used with a gatekeeper. You can specify either a prefix
151 ; or E.164 this endpoint is responsible for terminating.
153 ; Example: The H.323 alias 'det-gw' will tell the gatekeeper
154 ; to route any call with the prefix 1248 to this alias. Keyword
155 ; e164 is used when you want to specifiy a full telephone
156 ; number. So a call to the number 18102341212 would be
157 ; routed to the H.323 alias 'time'.
170 ; Inbound H.323 calls from BillyBob would land in the incoming
171 ; context with a maximum of 4 concurrent incoming calls
174 ; Note: If keyword 'incominglimit' are omitted Asterisk will not
175 ; enforce any maximum number of concurrent calls.
185 ; Outbound H.323 call to Larry using SlowStart
