Anyone considering VoIP using the ESP32-LyraT

Postby mikemoy » Fri Aug 17, 2018 10:54 am

I have been playing with the ESP32-LyraT V4.3 kit. Its really a nice kit.
I've developed a VoIP device for a client, but it uses a $130 VoIP module.

There are others like this as well, but typically the same cost.

VoIP is really not CPU demanding. I know the ESP32 could handle it no problem. I am curious if any of you out there have considered using the ESP32 as a VoIP Phone. So far the best open source thing for this was been http://www.pjsip.org/
But whew, thats a huge nugget to sink your teeth into to get working on the ESP32.

I know of some people (outside of this forum) who are developing a VoIP phone using the ESP32, so it certainly is possible. No idea what stack they're using, however.

Have them PM me. Depending on how it is, It may be worth buying it.

I'm also interested, for now the closest I found was https://github.com/chrta/sip_call but it would be interesting if it could be used with ESP32 ADF

Yes, I found that too and tried it but could not get it to do anything toggling GPIO0.

Does anyone suceeded to make some kink of SIP phone with ESP32 yet? it seems that the Wiphone ESP32 is using sip call but they don't share their code even if they say that it's an open source project.

https://hackaday.io/project/159811-esp32-wiphone

Anyone know some library I could use?

Thanks
