PinePhone as DIY SIP Gateway - Thoams131 - 08-21-2021
Hi!
Today I thought of using my PinePhone as a SIP-Gateway. It might be an interesting usage of a PP.
I assume the AT-Commands are only used for commands and the high-bandwidth-stuff goes through another communication channel? What protocol is used for voice? Do you know existing OpenSource Software which could connect a EG25-G (or other modules) to SIP?
To be totally honest, I think the project will fail due to my time management, but still I am interested in gathering first information, maybe also for someone else who wants to continue it ...
Thanks!
Thomas

There are SIP clients available, but none that work well yet - Twinkle, Linphone, etc. None have been optimized for mobile.

Hi!
I thought of a SIP Gateway, not a SIP-Client. Same Question here - sadly no good answer yet and some valuable comments are deleted
Seems like Asterisk is a commonly used Server-Software and there are some drivers for eg. Huawei Surfsticks available. So the only task would probably be to write a Module for the Baseband.
I think I currently won't have the time to make it, still some valuable input for someone else who considers doing it. (maybe my future self)
Best Regards!

It used to be possible on the OpenMoko with asterisk. Have a look at chan-quectel which is targeting similar quectel modem modules, and seems a fair starting point:

The trick will probably be sorting out the audio routing/configuration - Megous has the best description I've seen of how the routing works, or at least can work - I'm not sure if the distros are all doing it the same way.
