TREO 750v - VOICE (Phone Call) while TETHERING to PC/MAC (Dial-up Networking BT/USB)

[drakmog]

Anyone know how to be able to Talk on the Phone (Using Voice) while tethering to a PC / Mac , I know I can talk on the phone while using PIE and other internet based applications on the Treo, but NOT WHEN I HAVE IT TETHERED via Dial-up Networking (either via Bluetooth or USB). Basically I have tried both, and am using a MacBook Pro, and successfully tethered to the internet through both BT and USB but it HANGS UP if I make a call (and I presume it hangs up when I receive a call), but either way it does not treat the TETHERING the same as using INTERNET on the Treo, is this just some Registry entry thats causing the problem or something?

Please help I have been trying 10098098034298 things to get it to work; however I only have a VERY limited knowledge of Windows Mobile 5.0 and am pretty useless. If someone could even just give me insight on what settings or registry entry(ies) deal with this I could play around with it an post any results once I stumble upon them...

Thank you so much in advance!!!!!!!!!

It all depends on the network connection you have.

GSM/GPRS doesnt support Voice and Data where UMTS does.

Make sure that you have a 3G connection.

Yes I do have a 3G connection, this same thing (Tethering when using Voice) works on my LG CU500 flawlessly both when using USB and BLUETOOTH to tether, no drop in speeds and voice is crystal clear.

Not sure if its the way in which I am dialing up or something, or if its some bug in the 750. let me know if you guys can helop. THANKS!@!

Go to Menu>Preferences>Phone Settings and select the Services tab. Select the band selection and make sure to turn off auto and bind to UMTS only. If you are in auto and connected to GSM network and try to place a call while connected to DUN, thte call should suspend for a total of 13 minutes before disconnecting. If you are selected to strict UMTS then you should be OK for DUN and voice.
