; Inter-Asterisk eXchange v2 (IAX2) Channel Driver configuration
|

|
|
; This configuration is read when the chan_iax2.so module is loaded, and is

|

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
|
|
|
|
;
|
|
; You can adjust several parameters relating to the jitter buffer. The jitter
|
|
; buffer's function is to compensate for varying network delay.
|
|
;
|
|
; All of the jitter buffer settings are in milliseconds. The jitter buffer
|
|
; works for INCOMING audio only - 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.
|
|
;
|
|
; 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.

; There are three authentication methods that are supported: md5, plaintext,

|
|
; 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. There is no
|
|
; default unless set here in the [general] section. Only md5 and rsa support
|
|
; media encryption.

|

|

;

;
|

|
|
;forceencryption=yes
|
|
;
|
|
|
|
; This option defines the maximum payload in bytes an IAX2 trunk can support at
|
|
; a given time. The best way to explain this is to provide an example. If the
|
|
; maximum number of calls to be supported is 800, and each call transmits 20ms
|
|
; frames of audio using ulaw:
|
|
;
|
|
; (8000hz / 1000ms) * 20ms * 1 byte per sample = 160 bytes per frame
|
|
;
|
|
; The maximum load in bytes is:
|
|
;
|
|
; (160 bytes per frame) * (800 calls) = 128000 bytes
|
|
;
|
|
; Once this limit is reached, calls may be dropped or begin to lose audio.
|
|
; Depending on the codec in use and number of channels to be supported this value
|
|
; may need to be raised, but in most cases the default value is large enough.
|
|
;
|
|
; trunkmaxsize = 128000 ; defaults to 128000 bytes, which supports up to 800
|
|
; calls of ulaw at 20ms a frame.
|
|
|
|
; With a large amount of traffic on IAX2 trunks, there is a risk of bad voice
|
|
; quality when allowing the Linux system to handle fragmentation of UDP packets.
|
|
; Depending on the size of each payload, allowing the OS to handle fragmentation
|
|
; may not be very efficient. This setting sets the maximum transmission unit for
|
|
; IAX2 UDP trunking. The default is 1240 bytes which means if a trunk's payload
|
|
; is over 1240 bytes for every 20ms it will be broken into multiple 1240 byte
|
|
; messages. Zero disables this functionality and let's the OS handle
|
|
; fragmentation.
|
|
;
|
|
; trunkmtu = 1240 ; trunk data will be sent in 1240 byte messages.
|
|
|
|
; trunkfreq sets how frequently trunk messages are sent in milliseconds. This
|
|
; value is 20ms by default, which means the trunk will send all the data queued
|
|
; to it in the past 20ms. By increasing the time between sending trunk messages,
|
|
; the trunk's payload size will increase as well. Note, depending on the size
|
|
; set by trunkmtu, messages may be sent more often than specified. For example
|
|
; if a trunk's message size grows to the trunkmtu size before 20ms is reached
|
|
; that message will be sent immediately. Acceptable values are between 10ms and
|
|
; 1000ms.
|
|
;
|
|
; trunkfreq=20 ; How frequently to send trunk msgs (in ms). This is 20ms by
|
|
; default.
|
|
|
|
; 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.

|

|
|
; 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. If encryption is used (applicable to
|
|
; md5 and rsa only), a secret must be provided.
