Full ngrep log attached.
In the INVITE OpenSEr sends to your provider is appears:
## U 78.45.146.34:5060 -> 212.34.169.220:5060 INVITE sip:1217773456@212.34.169.220:5060 SIP/2.0. Record-Route: sip:78.45.146.34;ftag=6613ce14;lr. To: sip:1217773456@78.45.146.34. From: 58.68.96.11sip:test@78.45.146.34;tag=6613ce14. Call-ID: 757a270529254e41. ... Contact: sip:test@72.55.124.23:5060 <---- **1**
But in the BYE from your provider it appears:
## U 212.34.169.220:5060 -> 78.45.146.34:5060 BYE sip:test@78.45.146.34 SIP/2.0. <---- **2** Route: sip:78.45.146.34;ftag=6613ce14;lr. From: sip:1217773456@78.45.146.34;tag=04093807084639921117967993. Call-ID: 757a270529254e41. To: 58.68.96.11sip:test@78.45.146.34;tag=6613ce14. ...
That is wrong, the **2** field should be the same as **1** in order to OpenSer route the BYE to EyeBeam. Because the URI is 78.45.146.34 (OpenSer's IP) then the BYE arrives to OpenSer, it reads "Route: 78.45.146.34" so it deletes the "Route" header and sends again the BYE to himself. But this time there is not a "Route" header so the message is NOT in dialog.
I'd like to insist on this. The problem is there: the provider SHOULD send the BYE (in-dialog BYE containing "Route" header) to the URI indicated in the "Contact" header that OpenSer sent to provider. But instead of that, the provider sens the BYE to a wrong URI (sip:test@78.45.146.34).
Could you do a ngrep when a call from PAP2 to other PAP2? ngrep -d any -P ' ' -W byline -T -t "$*" udp port 5060
