A is the voip customers B is ser proxy C is the PSTN gateway 7331.881781 A -> B SIP/SDP Request: INVITE sip:0828963359@voip.prova.it, with session description 7331.883158 B -> A SIP Status: 407 Proxy Authentication Required 7331.987931 A -> B SIP Request: ACK sip:0828963359@voip.prova.it 7331.988081 A -> B SIP/SDP Request: INVITE sip:0828963359@voip.prova.it, with session description 7332.018157 B -> A SIP Status: 100 trying -- your call is important to us 7332.018602 B -> C SIP/SDP Request: INVITE sip:0828963359@C:5060, with session description 7332.114175 C -> B SIP Status: 100 Trying 7332.176249 C -> B SIP Status: 183 Session Progress 7332.177555 B -> A SIP Status: 183 Session Progress 7333.637122 C -> B SIP/SDP Status: 183 Session Progress, with session description 7333.638364 B -> A SIP/SDP Status: 183 Session Progress, with session description 7377.818129 B -> A SIP Status: 408 Request Timeout 7377.825608 B -> C SIP Request: CANCEL sip:0828963359@C:5060 7377.857091 A -> B SIP Request: ACK sip:0828963359@voip.prova.it 7377.897414 C -> B SIP Status: 200 OK 7377.898809 C -> B SIP Status: 487 Request Terminated 7377.899679 B -> C SIP Request: ACK sip:0828963359@C:5060

Should this behavior be triggered by some misconfiguration in my ser.cfg or it is only about the PSTN gateway not sending 200 OK?
