For reference I solved the problem. My UDP range was set wrong. My firewall
was not forwarding all the ports in the required range. Monowall works with
mitel 5055 phones and SIP with an sme 5.6 server with MKC voip phone
software installed.

I am already committed to this SIP service.(http://www.mkcnetworks.com/) We
have a server and many clients running on them at our office. We have a PSTN
so we have complete control over our VoIP network. It is just the
telaworker(phone outside the lan) phone we are experiencing a problem with.
I am hoping someone ells has run a Mitel 5055 sip phone with monowall. If
all ells fail we can go back to the Linksis router as it did work. But
monowall is about 99% better so I want to stick with it if I can.

An other approach to this it to avoid SIP altogether and use IAX2 based
VOIP providers like Voicepulse Connect, NuFone, or VOIPJet. You'd need
as Asterisk iPBX server at your location to handle the local end, but
you'd only have to open up one port (4569) and you'd have a
monsterously powerful system. I use both Asterisk and m0n0wall in my
home office. Both are incredibly powerful open source projects.
