Hi! First of all, I have to say that I am using PJSIP to negotiate a MSRP ICE session (it just has small changes in the encoding of the SDP). However, I am now experiencing a problem when receiving the re-INVITE: the on_rx_offer callback is not called when the re-INVITE is received, and I am not understanding why. By analysing PJSIP code, I see that the only place where such callback is used is in sip_inv.c's *inv_check_sdp_in_incoming_msg* method. Am I right? However, that method is called by one of the following: mod_inv_on_rx_request inv_respond_incoming_update inv_handle_update_response inv_respond_incoming_prack inv_on_state_calling inv_on_state_early inv_on_state_connecting inv_on_state_confirmed I don't know which one of these was supposed to be called in the "usual" scenario (receive a re-invite after a successful INVITE / 100 / 180 / 200 / ACK transaction occurred). Which one is it? However, the problem seems to be that, in sip_endpoint.c's endpt_on_rx_msg, the module *mod_ua_on_rx_request* "consumes" this reINVITE [it calls *pjsip_dlg_on_rx_request*, which in turn calls *mod_inv_on_rx_request* - but in this method there's an if which checks if the method ID is invite (as this is a reINVITE, it is), and returns true, thus handling/consuming the reINVITE] before it is sent to one of the methods above that would possibly call the desired *inv_check_sdp_in_incoming_msg* method, and thus *on_rx_offer callback*. I attached both the log and the capture I made. Any help on understanding why the on_rx_offer callback is not being called will be greatly appreciated.
