Hi I am trying to setup the IVM Answering Attendant VOIP application to receive calls from a Callcentric acoount. I entered correct username, password, and callcentric's SIP server but receive error messages about Incorrect Authentication when registering the number. The Express Talk phone registers itself correctly in 100% cases with the same settings. What can be the reason? thanks. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Logs: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 14:58:34 UDP Packet Received from 204.11.192.22:5060 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< SIP/2.0 407 Proxy Authentication Required v: SIP/2.0/UDP 216.191.158.46:63768;rport=63768;branch=z9hG4bK12560 f: <sip:xxxxxxxxx10@callcentric.com>;tag=655 t: <sip:xxxxxxxxx10@callcentric.com> i: 1190055513-2560-VMWAREXP@192.168.2.102 CSeq: 2 REGISTER Proxy-Authenticate: Digest realm="callcentric.com", domain="sip:callcentric.com", nonce="bd014ab8a9067832bfd8dcc47952261d", opaque="", stale=TRUE, algorithm=MD5 l: 0 ---------------------------------------------------------------- 14:58:34 UDP Packet Sent to 204.11.192.22:5060 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> REGISTER sip:callcentric.com SIP/2.0 Via: SIP/2.0/UDP 216.191.158.46:63768;rport;branch=z9hG4bK32560 Max-Forwards: 20 To: <sip:xxxxxxxxx10@callcentric.com> From: <sip:xxxxxxxxx10@callcentric.com>;tag=655 Call-ID: 1190055513-2560-VMWAREXP@192.168.2.102 CSeq: 3 REGISTER Contact: <sip:xxxxxxxxx10@216.191.158.46:63768>;expires=3600;q=0.20 Proxy-Authorization: Digest username="xxxxxxxxx10",realm="callcentric.com",nonce="bd014ab8a9067832bfd8dcc47952261d",uri="sip:callcentric.com",response="d14f30b49ead6aadf0426ffd20b8edd4",opaque="",algorithm=MD5 User-Agent: NCH Swift Sound IVM Answering Attendant 4.03 Content-Length: 0 ---------------------------------------------------------------- 14:58:34 UDP Packet Received from 204.11.192.22:5060 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< SIP/2.0 403 Incorrect Authentication v: SIP/2.0/UDP 216.191.158.46:63768;rport=63768;branch=z9hG4bK32560 f: <sip:xxxxxxxxx10@callcentric.com>;tag=655 t: <sip:xxxxxxxxx10@callcentric.com> i: 1190055513-2560-VMWAREXP@192.168.2.102 CSeq: 3 REGISTER l: 0
