9 ;tos_audio=ef ; Sets TOS for RTP audio packets.
10 ;cos_audio=5 ; Sets 802.1p priority for RTP audio packets.
12 ; You may specify a global default AMA flag for iaxtel calls. It must be
13 ; one of 'default', 'omit', 'billing', or 'documentation'. These flags
14 ; are used in the generation of call detail records.
18 ; You may specify a default account for Call Detail Records in addition
19 ; to specifying on a per-user basis
23 ; You can fine tune codecs here using "allow" and "disallow" clauses
24 ; with specific codecs. Use "all" to represent all formats.
27 ;allow=all ; turns on all installed codecs
28 ;disallow=g723.1 ; Hm... Proprietary, don't use it...
29 ;allow=gsm ; Always allow GSM, it's cool :)
30 ;allow=ulaw ; see doc/rtp-packetization for framing options
32 ; User-Input Mode (DTMF)
34 ; valid entries are: rfc2833, inband, cisco, h245-signal
38 ; Default RTP Payload to send RFC2833 DTMF on. This is used to
39 ; interoperate with broken gateways which cannot successfully
40 ; negotiate a RFC2833 payload type in the TerminalCapabilitySet.
41 ; To specify required payload type, put it after colon in dtmfmode
48 ; DISCOVER - Find the Gk address using multicast
49 ; DISABLE - Disable the use of a GK
50 ; <IP address> or <Host name> - The acutal IP address or hostname of your GK
54 ; Tell Asterisk whether or not to accept Gatekeeper
55 ; routed calls or not. Normally this should always
56 ; be set to yes, unless you want to have finer control
57 ; over which users are allowed access to Asterisk.
62 ; When the channel works without gatekeeper, there is possible to
63 ; reject calls from anonymous (not listed in users) callers.
64 ; Default is to allow anonymous calls.
66 ;AcceptAnonymous = yes
68 ; Optionally you can determine a user by Source IP versus its H.323 alias.
69 ; Default behavour is to determine user by H.323 alias.
73 ; Default context gets used in siutations where you are using
74 ; the GK routed model or no type=user was found. This gives you
75 ; the ability to either play an invalid message or to simply not
76 ; use user authentication at all.
80 ; Use this option to help Cisco (or other) gateways to setup backward voice
81 ; path to pass inband tones to calling user (see, for example,
82 ; http://www.cisco.com/warp/public/788/voip/ringback.html)
84 ; Add PROGRESS information element to SETUP message sent on outbound calls
85 ; to notify about required backward voice path. Valid values are:
86 ; 0 - don't add PROGRESS information element (default);
87 ; 1 - call is not end-end ISDN, further call progress information can
88 ; possibly be available in-band;
89 ; 3 - origination address is non-ISDN (Cisco accepts this value only);
90 ; 8 - in-band information or an appropriate pattern is now available;
93 ; Add PROGRESS information element (IE) to ALERT message sent on incoming
94 ; calls to notify about required backwared voice path. Valid values are:
95 ; 0 - don't add PROGRESS IE (default);
96 ; 8 - in-band information or an appropriate pattern is now available;
99 ; Generate PROGRESS message when H.323 audio path has established to create
100 ; backward audio path at other end of a call.
101 ;progress_audio = yes
103 ; Specify how to inject non-standard information into H.323 messages. When
104 ; the channel receives messages with tunneled information, it automatically
105 ; enables the same option for all further outgoing messages independedly on
106 ; options has been set by the configuration. This behavior is required, for
107 ; example, for Cisco CallManager when Q.SIG tunneling is enabled for a
108 ; gateway where Asterisk lives.
109 ; The option can be used multiple times, one option per line.
110 ;tunneling=none ; Totally disable tunneling (default)
111 ;tunneling=cisco ; Enable Cisco-specific tunneling
112 ;tunneling=qsig ; Enable tunneling via Q.SIG messages
114 ; Specify how to pass hold notification to remote party. Default is to
115 ; use H.450.4 supplementary service message.
116 ;hold=none ; Do not pass hold/retrieve notifications
117 ;hold=notify ; Use H.225 NOTIFY message
118 ;hold=q931only ; Use stripped H.225 NOTIFY message (Q.931 part
119 ; ; only, usable for Cisco CallManager)
120 ;hold=h450 ; Pass notification as H.450.4 supplementary
123 ;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
124 ; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of a
125 ; H323 channel. Defaults to "no". An enabled jitterbuffer will
126 ; be used only if the sending side can create and the receiving
127 ; side can not accept jitter. The H323 channel can accept jitter,
128 ; thus an enabled jitterbuffer on the receive H323 side will only
129 ; be used if the sending side can create jitter and jbforce is
132 ; jbforce = no ; Forces the use of a jitterbuffer on the receive side of a H323
133 ; channel. Defaults to "no".
135 ; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
137 ; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
138 ; resynchronized. Useful to improve the quality of the voice, with
139 ; big jumps in/broken timestamps, usualy sent from exotic devices
140 ; and programs. Defaults to 1000.
142 ; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of a H323
143 ; channel. Two implementations are currenlty available - "fixed"
144 ; (with size always equals to jbmax-size) and "adaptive" (with
145 ; variable size, actually the new jb of IAX2). Defaults to fixed.
147 ; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".
148 ;-----------------------------------------------------------------------------------
150 ; H.323 Alias definitions
152 ; Type 'h323' will register aliases to the endpoint
153 ; and Gatekeeper, if there is one.
155 ; Example: if someone calls time@your.asterisk.box.com
156 ; Asterisk will send the call to the extension 'time'
157 ; in the context default
160 ; exten => time,1,Answer
161 ; exten => time,2,Playback,current-time
163 ; Keyword's 'prefix' and 'e164' are only make sense when
164 ; used with a gatekeeper. You can specify either a prefix
165 ; or E.164 this endpoint is responsible for terminating.
167 ; Example: The H.323 alias 'det-gw' will tell the gatekeeper
168 ; to route any call with the prefix 1248 to this alias. Keyword
169 ; e164 is used when you want to specifiy a full telephone
170 ; number. So a call to the number 18102341212 would be
171 ; routed to the H.323 alias 'time'.
184 ; Inbound H.323 calls from BillyBob would land in the incoming
185 ; context with a maximum of 4 concurrent incoming calls
188 ; Note: If keyword 'incominglimit' are omitted Asterisk will not
189 ; enforce any maximum number of concurrent calls.
199 ; Outbound H.323 call to Larry using SlowStart
