annotate sip-in/mgw_resp.c @ 152:7176dc850d7a

sip-in hold/retr error handling: simply send BYE Because we know that the SIP state is CONNECTED at the time of any such error event, we can call initiate_bye() instead of disconnect_sip(), and thereby get rid of struct gsm_mncc_cause which will never be used in this scenario anyway.
