Yes. That is possible. Its just a standard gateway on a sip profile. /b On Jul 30, 2008, at 11:04 AM, Simon Shaw wrote:

Is it possible to configure FS such that it will only handle SIP Register messages internally and will pass all other messages via a SIP trunk to an existing PBX. This would be very useful to gradually move existing IP phones over to FS. The stage after that would be to define that certain phones have all their call processing done on the FS box.
