Hello Everybody, I am experiencing a little nuisance (mostly) with calls TO phone number hosted by PSTN (versus SIP) providers: Outbound calls (initiated by my UAC - iPhone with 1.8.10) TO a PSTN number that are "terminated" by the callee (i.e. the PSTN callee hangs up) do not receive the callStateChange to PJSIP_INV_STATE_DISCONNECTED. This is particularly awkward e.g. in a call-waiting situation, where the waiting party is the callee in the sense described before. Inbound calls received from PSTN numbers receive the callStateChange to PJSIP_INV_STATE_DISCONNECTED just fine when the PSTN caller hangs up. Is there anything that I should fix on my side? - What is the recommended tactic to cope with this? Thanks in advance! Best regards, Thomas
