Some of our users have GSM and need to be called when a call comes in from the PSTN. I was wondering if some VoIP provider offers the following:
- all SIP phones (soft and hard) register with the VoIP provider
- I add some extensions for the GSM phones
- all those extensions are made into a group extension
- The Linksys is set up to call that group extension, and ring all phones, whether IP or GSM.
