Hello Guys,

I just would like to know if Asterisk accept within SIP the P-Access-Network-Info header and if it’s possible to get it with function SIP_HEADER() ?

I expect to have a telecom equipment that will send it through SIP to Asterisk and would like to ensure I would be able to get and catch it on Asterisk.

Thanks for your feedback!

Best Regards


Yes, as long as you are only interested in the value in the initial INVITE.

Yes I’m only interested about this value in the INVITE. This field would be to forward “location number address signal” from ISUP SS7 protocol to SIP. I need to to catch this value and store it in CDR so from what you told me it shouldn’t be an issue to get it.
