Hi! a full ngrep trace would be helpfull
"ngrep -t -d any -p "" port 5060"
What looks strange at first sight that there is a CANCEL after the 200 OK.

Hello,
I have problems calling from my phones connected to openser to grandstream
phones on another university to ser. Problem is, that my openser generates
a "CANCEL" SIP packet sent to grandstream phone, but no CANCEL received
from my phone. Wireshark shows something like this:
1189587144.843962 158.195.15.100 -> 158.197.16.77 SIP/SDP Status: 200 OK,
with session description
1189587144.845528 158.197.16.77 -> 158.195.15.100 SIP Request: CANCEL
sip:[EMAIL PROTECTED]
1189587144.853654 158.195.15.100 -> 158.197.16.77 SIP Status: 200 canceling
Communication before is OK. 158.197.16.77 is my openser server and
158.195.15.100 is peers phone.
Any idea, why openser can generate this packet? Can openser generate a
SIP packet not received from client?
Calling from my phone to another phone on same university works well.
Thank you.
SAL
