If one office has only a single SIP phone then you don't trunk to them
via IAX. You let them connect directly to the ITSP for their
outgoing/incomming PSTN calls. You program dialplan logic on your *
boxen to connect to that SIP extension via IP. 

You could get them a free SIP account like FWD, SIPPhone, etc and use
that to setup presets for calling from that extension to your other
offices directly via IP. It'd take more of a phone than a Grandstream,
but then they're pretty simple for business use anyway. I like my
Polycom IP600. I also like my Zultys 4x5.

If the end, if it were my project, I'd look into Asterisk on a small
form factor/embedded system like a Soekris Engineering box...even for
single extension offices. That'd give you a low cost way to offer
comparable programmability and dialplan logic in all cases. Also local
voicemail, if that's of any value.
