[Freeswitch-users] FreeSwitch and Cisco 7941 IP Phone ( INVITE port number )

After commenting-out the mentioned code block, the INVITE is send to port
5060 so that the call gets established.


But still:


After hanging up one of the 7941 (call was established between 2 of them),
the BYE message towards the other 7941 is still send to the higher port
number ( so the corresponding 7941 does not end the line )


Thanks and regards

Please see http://jira.freeswitch.org/browse/FS-2773 I reported.

The mentioned code is now commented in FS, so nat is no longer assumed.

This is about FreeSwitch 1.0.6 (Windows Build) and Cisco 7941 IP Phone, and
the same issue was recently reported by another subscriber of this list
(Michael W. Lucas).
Anyhow, I attach traces so that maybe someone can look into it.
The 7941 successfull REGISTER in FreeSwitch, and is able to call another
The softphone is not able to call the 7941, and this is because the INVITE
from FreeSwitch towards 7941 goes to the UDP port that the 7941 was using
during REGISTER (high port number, instead of 5060)
I compared this with traces for 3CX where all works fine. 3CX sends the
INVITE towards 7941 to UDP port 5060, and the 7941 seems to like this :-)
Please find attached the REGISTER / INVITE traces for booth 3CX and
FreeSwitch, and also the FreeSwitch console-output from"sofia profile
internal siptrace on"
Thanks for review !
