[Asterisk-Users] Extra parameters in SIP URIs

[Skuse, Phil]

Yes. I wrote a patch for this so that I could use * with our Snowshore A1.
The patch has been included in asterisk. 

In my case I needed to send to

sip:606 at 192.168.0.1;voicexml=http://192.168.0.2/snowshore/test.vxml

Here is the relevant part of extensions.conf

exten =>
606,1,Setvar,VXML_URL=voicexml=http%3A%2F%2F192.168.0.2%2Fsnowshore%2Ftest.v
xml
exten => 606,2,Dial,sip/192.168.0.1

The variable VXML_URL should probably be renamed URI_PARAM or something more
generic.

Subject: [Asterisk-Users] Extra parameters in SIP URIs


Hello,

I've seen that Nuance SIP audio provider supports additional information
(parameters and extra headers) in SIP URIs, using the format:

sip:user:password at host:port;uri-param1;uri-param2?header1&header2

For example,

sip:1234 at myserver.com;extra_header=Uui?Uui=Hello

Does Asterisk support this format?

Is there a way to retrieve the value of these additional headers, and then
decide the action (Dial, Playback, etc.) as desired? (I'm thinking in an "if
... then ... elsif ... else ...").

Thanks,
Cerrajetto
