How to get timeout parameter sent by a gateway

Asterisk Asterisk Support

This is my first post here

I have an Asterisk Box (A) configured to handle traffic received from other SIP gateways (B). The box basically reroutes traffic to another SIP gateway©.

The Gateway B sends timeout values to Asterisk (A).

My problem is how do I read the parameters sent by B to A.

This is what Gateway (B) sends to Asterisk A.
SIP/1342233343@192.168.10.254|60|HRgrL(852:61000:30000)

I need to retrieve the timeout value 852 and pass on to Gateway C.

Is there any variable like ${EXTN} or something that stores the timeout parameter in A ?

thanks for you help

I have been trying to use function:
,Set(time_out=${SIP_HEADER(options):2})
,Set(time_out=${SIP_HEADER(VXML_URL))
…
…
But nothing is working for me.

I don’t see those parameters in SIP headers ( with sip debug turned on).

So I was wondering if those paramters are passed via SIP headers or in a different way.

I will be glad if someone could point me to right direction…

thanks!
