There are some SIP clients that work, but in general 3rd-party is responsible for certification.

The HP iPAQ 510 is supported with CallManager 5.1. You can look for HPiPAQ500seriesVoiceMessenger and this one uses SIP.

There is a WM 6 SIP Stack Free Configuration Tool out there called SIP Conf Tool 2.0.1, never used it, but it

might help to get an idea.

IP Blue has a softphone for the Windows Mobile OS which is based on the Cisco SCCP protocol.

If you want to develop one, try this link and see if you can find something related to what you need:
