  • Resolution set to fixed
  • Status changed from new to closed

(In [3215]) Fixes #1047 (Don't send UPDATE if remote doesn't support it (thanks Bogdan Krakowski for the report)) and fixes #1097 (Support sending UPDATE without SDP). Details:

  • Session timer fixes:
    • will look at remote capability in Allow header
    • if UPDATE is supported, will send UPDATE without SDP first. If this fails, will send UPDATE with SDP
    • otherwise will send re-INVITE
  • PJSUA-LIB will look at dialog's remote capability to determine whether re-INVITE or UPDATE should be sent to change default addresses after ICE negotiation.
  • pjsip_inv_update() now allows NULL offer, in which case the UPDATE will be sent without SDP.
