One thought on - How Do I Retrieve The Call-ID From The SIP INVITE When Using Originate On PJSIP?

• Please Disregard. I found the solution.

  In case anyone else runs into this, use (CHANNEL(pjsip,call-id)) and not the PJSIP_HEADER(read, …)

  Using chan_sip, we are able to retrieve the Call-ID using the SIPCALLID channel variable. This works for both inbound and outbound (Originated) calls.

  For PJSIP this variable doesn’t get set. Instead, for inbound calls we retrieve the Call-ID from the INVITE packet using the PJSIP_HEADER(read,Call-ID,1). However, this doesn’t work for outbound calls because the datastore hasn’t been set.

  [08/23 07:14:41.185] DEBUG[59544] res_pjsip_header_funcs.c: There was no datastore from which to read headers.
  [08/23 07:14:41.185] DEBUG[59556][C-00000007] pbx_variables.c: Function PJSIP_HEADER(read,Call-ID,1) result is ‘(null)’

  Not being able to access the datastore for Originated PJSIP calls even though there is already an event: newchannel seem like something was missed with the PJSIP outbound calls.

  Any suggestions?

  Have a great day!
