Our network is replacing all polycom codecs with Cisco C series. I noticed I have a problem connecting when dialing from a C40,Cc60 to a polycom VSX 8000,VSX 7000e some of the older polycoms. I have polycoms registered to VCS. With the polycom gatekeeper function ON , the NAT feature has to be turned off in order to recieve calls from the C40, C60. This is a problem because if another polycom tries to reach that codec with NAT off it won't connect. I would like to keep the NAT feature ON with the Polycom when accepting call form C40, C20. Is this a problem the VCS can correct? Is there a string I can use in the Tandberg calling format? I know old polycoms to Tanberg string -IP address ##1234.
thanks in advance
