I want to build a VoIP Phone with STM32F4. Does anybody know, if there is a small SIP-Stack that can easily used with microcontroller.
Thanks Marc
Hello Marc,
Maybe it is a little bit late, but some SIP stack for microcontroller are:
PJSIP, Sofia, BareSIP, reSIProcate, etc.
PJSIP has a good porting guide and a small footprint.
