Hello, The symbian_ua failed to register successfully. Instead, it returns: pjsua_acc.c SIP registration error: Credential failed to authenticate (PJSIP_EFAILEDCREDENTIAL [status=171100] Both symbian_ua on emulator and symbian_ua on actual device (N82) will see the same error. However, strangely, pjsua of release 0.8.0 can register successfully on Windows, using the same sip credentials. Here is the packet flow captured: |Time | 10.6.104.18 | proxy | |0.000 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 43983) | |(5060) ------------------> (5060) | |0.123 | Status: 401 Unautho |SIP: Status: 401 Unauthorized - no credentials are provided in the request (0 bindings) | |(5060) <------------------ (5060) | |0.503 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 43984) | |(5060) ------------------> (5060) | |0.591 | Status: 200 OK ( |SIP: Status: 200 OK (1 bindings) | |(5060) <------------------ (5060) | |0.887 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 43985) | |(5060) ------------------> (5060) | |0.981 | Status: 401 Unautho |SIP: Status: 401 Unauthorized - no credentials are provided in the request (0 bindings) | |(5060) <------------------ (5060) | |1.038 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 29318) | |(5060) ------------------> (5060) | |1.144 | Status: 401 Unautho |SIP: Status: 401 Unauthorized - no credentials are provided in the request (0 bindings) | |(5060) <------------------ (5060) | |1.384 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 43986) | |(5060) ------------------> (5060) | |1.482 | Status: 200 OK ( |SIP: Status: 200 OK (0 bindings) | |(5060) <------------------ (5060) | |1.718 | Request: REGISTER s |SIP: Request: REGISTER sip:proxy (CSeq: 29319) | |(5060) ------------------> (5060) | |1.810 | Status: 401 Unautho |SIP: Status: 401 Unauthorized - server-specified nonce should be uniquely generated (0 bindings) | |(5060) <------------------ (5060) | The above are facts gathered. I suspect that the error may be due to the existence of REGISTER requests with strange CSeq number. In the above capture, CSeq series of 43xxx seems to be normal. But the REGISTER with CSeq 29xxx seems to be quite strange and unnecessary. By the way, pjsua (rel 0.8.0) on Windows don't generate these kind of strange CSeq series in the REGISTER process. Thank you for shedding some lights on this issue! Wish you all a good day.
