Now that google has given the official obituary on GIZMO, this old post should be getting a lot more activity from folks such as myself that are searching for a GIZMO / SIP provider.

I need a replacement SIP phone service w/ call-in number that'll work on:
Nokia 770 & n800
Linksys wireless ip phone
Grandstream ht486 & 286
various Linux desktop computers, laptops & netbooks.

I'm just getting started on this quest, but so far Ekiga is looking like it may be a functional softphone on our desktops, where Linphone is not able to (on some) but still need the SIP call-in number & service.

Softphones are not at issue; it's the hardware adapters that we need to get back up & running.

I am in the US but it would be good to have functionality in Germany, Sweden, Abu Dhabi, South Africa, & Eastern Europe.
Vietnam would put frosting on the cake.

Comments & suggestions please? ... and thanks in advance.
