I don't believe the current GP phone is based on anything from
Counterpath/X-ten. When they originally launched SIPphone, they licensed
the X-Pro phone from X-ten, but the Gizmo Project softphone has always
been a completely different beast.

Later versions include the ability to sign up for one other service
provider AS WELL AS Gizmo Project/SIPphone, however I don't believe you
can ONLY use it through another provider, and GP does some odd things
with the Contact header that are... nonstandard.  When REGISTERING with
another provider, it uses a Contact header with a GP username/ip,
requiring that all calls be initially routed back through GP's servers.
They say this is for logging purposes, but it certainly makes for an
ugly data path.


We actually had to reconfigure our servers just to allow for the GP
users who would occasionally register directly.
