=== Description ===
This script can be used for interactive audio session or for scripting alarms. The script returns appropriate shell response codes for failed or successful sessions. The script can be setup to auto answer and auto hangup after predefined number of seconds, detects SIP negative response codes, missing ACK and the lack of RTP media after a session has been established.

Usage: sip_audio_session [options] [target-user@target-domain.com]

session and quit when Ctrl+D is pressed.

-p PASSWORD, --password=PASSWORD
Password to use to authenticate the local account.
This overrides the setting from the config file.

Display name to use for the local account. This
overrides the setting from the config file.
-o IP[:PORT], --outbound-proxy=IP[:PORT]
Outbound SIP proxy to use. By default a lookup of the
domain is performed based on SRV and A records. This
overrides the setting from the config file.
-s, --trace-sip Dump the raw contents of incoming and outgoing SIP
messages (disabled by default). The argument specifies
where the messages are to be dumped.
-t EC_TAIL_LENGTH, --ec-tail-length=EC_TAIL_LENGTH
Echo cancellation tail length in ms, setting this to 0
will disable echo cancellation. Default is 50 ms.

Default is 32kHz.

Comma separated list of codecs to be used. Default is
"speex,g711,ilbc,gsm,g722".
-S, --disable-sound Do not initialize the soundcard (by default the
soundcard is enabled).
-j, --trace-pjsip Print PJSIP logging output (disabled by default).
--auto-hangup Interval after which to hangup an on-going call
(applies only to outgoing calls, disabled by default).
If the option is specified but the interval is not, it
defaults to 0 (hangup the call as soon as it
connects).

(disabled by default). If the option is specified but
the interval is not, it defaults to 0 (answer the call
as soon as it starts ringing).
