multiple phones on sip(gate)

I have multiple Yealink phones on Sipgate all registered to the same
Sipgate free account and all ringing in on incoming calls. My devices
are listed as

Yealink T20P 91.---.---.--7:5061

Yealink T28P 91.---.---.--7:5063

There doesn't seem to be any conflict over port numbers, etc.

Is there an easy way of transferring calls between phones or intercom
calling between phones? I can do it by transferring to the SIP number,
which rings all the phones again, but it's a kludge.

A local (or hosted) PBX.

I was thinking along the lines of phone-to-phone calling, if I put the
IP addresses and/or ports of the phones into speed dial buttons?

If the phone allows you to do that, it should work. You would need
to put in a SIP URL, including the port number because you're using
non-standard port numbers for SIP. The address part of the URL can
be either a numeric IP address, or, if the phone is aware of your
name server, a named address. The phone must also be able to do a
transfer.

Some phones restrict the character set you can use - if you can only
put in a pure number, you're out of luck.

Note that that IP address you've tried to obscure there appears as

NNTP-Posting-Host: 91.125.227.237

in your message.

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
port numbers?)

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.
