Last week we upgraded to CCM 3.1(2c), including the firmware versions of the 7910 and 7960 phones. 3.1(1.2) for both phones.
Since the upgrade the IP phones that are inside the firewall cannot make calls outside the firewall or to each other. IP phones from the outside however can call the inside phones. Before the upgrade everything worked fine.
Permit IP any any has been opened up on the firewall along with a list of PIX supported protocols that was found in the Cisco site. Fixup for skinny and H323 is also turned on. We have tried a different PIX in a test bed and had the same problem. PIX is running 6.1.
Did you upgrade from CCM 3.0.(x) to 3.1(2c)? I had a similar problems when I upgraded my PIX to 6.1 when I was using CCM 3.1(1). In PIX, there is a problem with Fixup for Skinny with newer version of the CCM so I had to turned that off to make it work. According to TAC, this is a known bug but hasn't been published yet.
