Re: ARI Get Channel Variable

[Phil Mickelson <phil@xxxxxxxxxxxxxxx>]

We are using PJSIP.  And I was able to get the call id:  PJSIP_HEADER(read,call-id).

Thank you very much!  And thank you for your very fast response!

I'm trying to get the Call-ID from the SIP HEADER using getChannelVar.  When I pass SIP_HEADER() and anything as the variable I get Unable to read provided function.  If use Call-ID I get Provided variable was not found.

This is a connected call.  Is it not possible to get SIP HEADER information once it's connected?  Or, am I missing something?

Are you using chan_sip or chan_pjsip? If chan_pjsip then you need to use the PJSIP_HEADER function [1] instead. For instance the following returned the call-id for me:

PJSIP_HEADER(read,Call-ID)

How are you attempting to use the channel function [2]? For instance the following returned the call-id for me as well:

CHANNEL(pjsip,call-id)
