Hi folks,

[snip]

I think the requirements are
- must work in USA
- locked
- can register to VoIP provider (e.g. Sipgate) for inbound calls
- can use other providers (e.g. smslisto.com) for outbound calls
- has some form of routing dialplan

Any thoughts, please?

Cheers,
Chris

Other than your last requirement, most well known SIP phones will do all
those. A dialplan in terms of a call-routing script isn't something
I've really seen on phones, it's usually left to a PBX to handle.

Although as someone else has mentioned already, the Gigaset DECT IP
phones have a basic call routing dial plan in them based on the start of
numbers. I.E. you can point 07 numbers to one connection, 02 numbers to
another 01 numbers to another etc...etc...

It might also be worth looking at the Fritzbox routers as they have
basic PBX functionality such as this. Although not sure on a USA
version, they are primarily an ADSL device. You can disable the ADSL
modem part and use a LAN port as the WAN side though so in theory....

Actual phones that have dial plan settings, this is usually more about
barring certain types of numbers or reformatting numbers than anything
to do with call routing. On a phone you normally route a call out of
which ever SIP account you currently have selected (inbound calls to any
on the phone make it ring).

Paul.
