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: 58.68.96.11<sip: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: 58.68.96.11<sip: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 htink you have deleted, by error, some of the trace messages after the BYE,
maybe you though they were repeat messages (retransmited by timers and so).
Nooo, sorry, you don't see it in the trace because now it's localhost
connection (not ethX).
Try again the trace but with -d any (all the net devices, not just eth0).
ngrep -d any -P ' ' -W byline -T -t "$*" udp port 5060
