XDA2:Is there some software handler possible on GSM voice?

[fixxxer]

There's a need in mobile PC/GSM device which allows to put a software filter on voice which is transmitted via GSM network when talking.
Can it be done on XDA2 and if not which models will you suggest?
The filtering needs to be done on digital signal not packed to GSM packets, in both directions, during the talk - in realtime.
Thanks in advance.

This is impossible on XDA1,2,3 and Anextek SP230. Probably this is a limitation of PocketPC 2003 (even SE) OS. Wait for a device with a PPC 2005, maybe it would support this.

it IS possible.

but you must delete default Phone application and services. and then you can run your own implementation of phone features with filter or anything other inside the voice channels.

please note: default Phone is invoked by several services, you have to lock all these ways.
