31 ; Disable UDP checksums (if nochecksums is set, then no checkums will

38 ; enable "delayreject" which will delay the sending of authentication

43 ; You may specify a global default AMA flag for iaxtel calls. It must be
44 ; one of 'default', 'omit', 'billing', or 'documentation'. These flags
45 ; are used in the generation of call detail records.

67 ; channel with Set(CHANNEL(musicclass)=whatever) in the dialplan, and the peer
68 ; channel putting this one on hold did not suggest a music class.

83 ; Specify bandwidth of low, medium, or high to control which codecs are used

102 ; The jitter buffer works for INCOMING audio - the outbound audio
103 ; will be dejittered by the jitter buffer at the other end.

106 ; the jitter buffer at all.
108 ; forcejitterbuffer=yes|no: in the ideal world, when we bridge VoIP channels
109 ; we don't want to do jitterbuffering on the switch, since the endpoints
110 ; can each handle this. However, some endpoints may have poor jitterbuffers
111 ; themselves, so this option will force * to always jitterbuffer, even in this
114 ; maxjitterbuffer: a maximum size for the jitter buffer.
115 ; Setting a reasonable maximum here will prevent the call delay
116 ; from rising to silly values in extreme situations; you'll hear
117 ; SOMETHING, even though it will be jittery.
119 ; resyncthreshold: when the jitterbuffer notices a significant change in delay
120 ; that continues over a few frames, it will resync, assuming that the change in
121 ; delay was caused by a timestamping mix-up. The threshold for noticing a
122 ; change in delay is measured as twice the measured jitter plus this resync
124 ; Resyncing can be disabled by setting this parameter to -1.
126 ; maxjitterinterps: the maximum number of interpolation frames the jitterbuffer
127 ; should return in a row. Since some clients do not send CNG/DTX frames to
128 ; indicate silence, the jitterbuffer will assume silence has begun after
129 ; returning this many interpolations. This prevents interpolating throughout

141 ; Should we send timestamps for the individual sub-frames within trunk frames?
142 ; There is a small bandwidth use for these (less than 1kbps/call), but they
143 ; ensure that frame timestamps get sent end-to-end properly. If both ends of
144 ; all your trunks go directly to TDM, _and_ your trunkfreq equals the frame
145 ; length for your codecs, you can probably suppress these. The receiver must
146 ; also support this feature, although they do not also need to have it enabled.

204 ; If regcontext is specified, Asterisk will dynamically create and destroy

206 ; with us. The actual extension is the 'regexten' parameter of the registering
207 ; peer or its name if 'regexten' is not provided. More than one regexten

213 ; If we don't get ACK to our NEW within 2000ms, and autokill is set to yes,

215 ; only). This is used to keep things from stalling for a long time for a host
216 ; that is not available, but would be ill advised for bad connections. In
217 ; addition to 'yes' or 'no' you can also specify a number of milliseconds.
218 ; See 'qualify' for individual peers to turn on for just a specific peer.
222 ; codecpriority controls the codec negotiation of an inbound IAX call.
223 ; This option is inherited to all user entities. It can also be defined
224 ; in each user entity separately which will override the setting in general.
226 ; The valid values are:
228 ; caller - Consider the callers preferred order ahead of the host's.
229 ; host - Consider the host's preferred order ahead of the caller's.
230 ; disabled - Disable the consideration of codec preference altogether.

302 ; so that when you receive a call you set the Caller*ID to be what you want
303 ; instead of trusting what the remote user provides
305 ; There are three authentication methods that are supported: md5, plaintext,
306 ; and rsa. The least secure is "plaintext", which sends passwords cleartext
307 ; across the net. "md5" uses a challenge/response md5 sum arrangement, but
308 ; still requires both ends have plain text access to the secret. "rsa" allows
309 ; unidirectional secret knowledge through public/private keys. If "rsa"
310 ; authentication is used, "inkeys" is a list of acceptable public keys on the
311 ; local system that can be used to authenticate the remote peer, separated by
312 ; the ":" character. "outkey" is a single, private key to use to authenticate
313 ; to the other side. Public keys are named /var/lib/asterisk/keys/<name>.pub
314 ; while private keys are named /var/lib/asterisk/keys/<name>.key. Private
