Sorry my mistake. It is Version 8.9 on Cisco 7960 ( POS3-08-9-00).

I’d say it is much more likely a Cisco 7960 bug. Cisco’s SIP software is total crap. It’s too bad because their phones are physically very nice and very reliable. I’d verify what release you are on as a search of Cisco’s site doesn’t show a 7.9. It shows up to 7.5. 8 goes all the way to 8.9. In * land, we never went past 7.4 as anything after that had issues.

FreeSWITCH Version 1.0.head (git-9350fb9 2010-12-07 00-20-07 -0600)
I just install freeswitch and have two cisco 7960 phones (firmware sip 7.9) registered.
I can call out to our service provider or make 7960 call each other. They all work fine except this:
If I call into freeswitch echo test extension or check voicemail using one of Cisco 7960, the call will be droped after 30 seconds. By looking at SIP messages, it appears that After FS send out 200 OK to Cisco 7960, it never received ACK sip messages back and timeout. Here is the debug info in Cisco 7960:

Looks like cisco 7960 having trouble to process 200 OK message from FS.
Is this a possible FS bug? Does anybody know how to fix it?
By searching on the WEB, I can see that Asterisk 1.6 also has the same problem in some revisions and been fixed.
