It shouldn't be as complicated as that - normally if you're fiddling
with ports on a phone it will be the outgoing port, and even then you
really shouldn't need to. (Why do you think the OP is using non-standard
So the phone will still be "listening" on port 5060, so if one handset
can put a call on-hold, then "dial" another phone purely by IP address
then you'll be fine.
Of-course if there are NAT routers in-between the phones then you'll
very probably not be fine, however I'm guessing here that they're all
on the same LAN.
It would still be nicer to have a local/hosted PBX though - lots more
features - e.g. intercom which it's highly unlikely you'll be able
to do on direct IP dialling as typically you need to send an extra SIP
header to the phone to tell it to auto-answer in speakerphone mode.
