[asterisk-users] Windows Mobile 6 IAX/SIP client?

[Remco Barendse]

I just bought a HTC TyTn II phone, but unfortunately it doesn't even have 
a SIP client in it.

I tried the wiki searching for a SIP or IAX client but only found some 
PocketPC stuff (Windows Mobile 2003).

Does anyone know of a good quality SIP or IAX softphone that will run on 
Windows Mobile 6?

I only have a data subscription, no voice so the quality should be 
sufficient to be used constantly.

Thanks!!
