Inline Dialplan

Are you looking for inline actions in the dialplan?​

Description​

Allows you to specify a dialplan in code where you might normally specify an extension and dialplan.
Basic syntax is a comma-separated list of 'app:arg' pairs:

'app1:arg1,app2:arg2,app3:arg3' inline

Single quotes generally are necessary except in the case of a single app:arg pair with no spaces, e.g.:

uuid_transfer <uuid> playback:/foo.wav inline

The inline dialplan is a handy tool that allows for flexible application development.

Escaping​

If you have a complicated inline dialplan, you can occasionally run afoul of issues with commas. To avoid this issue, the inline dialplan allows you define the application delimiter:

'm:^:app1:arg1^app2:arg2^bridge:{origination_uuid=asdf,ignore_early_media_true}/sofia/gateway/mygw/1234' inline

Examples​

uuid_transfer​

A simple uuid transfer might look like this:

uuid_transfer 2bde6598-0f1a-48fe-80bc-a457a31b0055 'set:test=blah blah,playback:foo.wav' inline

Another application is to grabbed a parked channel and bridge to another channel:

uuid_transfer <parked_uuid> intercept:<other_uuid> inline

Originate​

A simple originate where the B leg is specified inline:

 originate sofia/gateway/my_gw/user@domain.com 'set:myvar=myvalue,info:,playback:foo.wav' inline

PortAudio​

A handy way to use PortAudio from the FreeSWITCH CLI is this:

 originate {absolute_codec_string=XXXX}sofia/default/foo@bar.com bridge:portaudio/auto_answer inline

See also: Dialplan_XML#Getting_Fancy_With_PortAudio

Note the lack of a leading / in the bridge string above. If you tried to do bridge:/portaudio/auto_answer the bridge would fail with CHAN_NOT_IMPLEMENTED because FreeSWITCH™ assumes the string between the ':' and the first '/' to be the channel type, and so if you have a leading slash the channel type is an empty string.SIP Profile

The dialplan parameter in the SIP profile can also be an inline dialplan. The standard entry is this:

<param name="dialplan" value="XML"/>

Customize it like this:

<param name="dialplan" value="inline:playback:woohoo.wav,hangup:BUHbye"/>

Note that you specify "inline:" at the beginning of the parameter and not at the end like you do when using the command line.
