I've tested several VoIP apps (SIP clients, Skype, etc.) on my Windows Mobile XV6700 phone and other Windows Mobiles and from what I understand the carrier forced the hardware manufacturers to block VoIP applications from using the earpiece for listening to the remote caller. You couldn't even use speakerphone. Instead, you were forced to use the backspeaker, a tiny low-quality speaker located on the back of the phone, which made phone quality horrendous when making VoIP calls. I'd have to flip the phone over when the person was talking due to low volume & quality, and then flip it back over to talk into the microphone. It was all but unusable.
Well glory glory hallelujah! I never thought the day would come when someone would come up with a solution. According to Teksoft, "After several years of tests and many questions in the development forum, we've finally did it: a tool to route the audio to the earpiece speaker is available, and we've released it as freeware." Woohoo! Now I can register my SIP client on my Windows Mobile to my Asterisk-based IP-PBX and make/receive VoIP calls.
