So I sniffed data from internal network and from DSL, then I started the call using the web management system of the SNOM. I see Asterisk sends to the phone: Via: SIP/2.0/UDP 192.168.60.53:3072;branch=z9hG4bK-igym6msxn88p;received=192.168.60.53;rport=3072 From: "Sekretariat" <sip:[email protected]>;tag=ts2ye4krhs To: <sip:[email protected];user=phone>;tag=as32fe51ba Call-ID: 313634303731393637343630373636-ex7145moy1mt CSeq: 2 INVITE Server: Asterisk PBX 16.2.1~dfsg-1+deb10u2 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces Contact: <sip:[email protected]:5060> Content-Length: 0 After about 6 seconds I get from the Telekom: Via: SIP/2.0/UDP 87.191.224.158:5060;received=87.191.224.158;rport=5060;branch=z9hG4bKPj43be873a-cf55-4348-8867-5c2bb97bd76a To: <sip:[email protected]>;tag=h7g4Esbg_p65544t1640719676m169304c9321s1_3514393582-932943693 From: <sip:[email protected]>;tag=4781eb96-b155-421e-8206-593d44c9f7c4 Call-ID: 478ba582-946c-46ac-984d-6f1835e3391b CSeq: 15716 INVITE Contact: <sip:[email protected];transport=udp> Record-Route: <sip:217.0.27.161;transport=udp;lr> P-Early-Media: sendrecv, gated Require: 100rel RSeq: 2 Content-Type: application/sdp Content-Length: 281 Allow: REGISTER, REFER, NOTIFY, SUBSCRIBE, PUBLISH, MESSAGE, UPDATE, PRACK, INFO, INVITE, ACK, OPTIONS, CANCEL, BYE Then I see Asterisk sends this to the phone: Via: SIP/2.0/UDP 192.168.60.53:3072;branch=z9hG4bK-igym6msxn88p;received=192.168.60.53;rport=3072 From: "Sekretariat" <sip:[email protected]>;tag=ts2ye4krhs To: <sip:[email protected];user=phone>;tag=as32fe51ba Call-ID: 313634303731393637343630373636-ex7145moy1mt CSeq: 2 INVITE Server: Asterisk PBX 16.2.1~dfsg-1+deb10u2 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces Contact: <sip:[email protected]:5060> P-Asserted-Identity: "03529529874" <sip:[email protected]> Content-Length: 0 So, it seems Asterisk receives from Deutsche Telekom _one_ "Ringing" and sends the phone _two_ "Ringing", the second one with the P-Asserted-Identity... Maybe help it to identify the problem?
