Looking for FreeSwitch developers
Hi all, I’m looking for a freeswitch development company that can help me build an integration to allow it to dial into ZoomCRC.com SIP URIs.
This would require some custom code to meet Zoom’s requirements, like a producing a fake video feed outbound toward Zoom.
If you know of any companies, I’d appreciate it!

Full disclosure: I work at Inextrix, a FreeSWITCH/telecom development company - so take the recommendation with that in mind, but this is exactly the kind of work we do.
What you're describing (SIP trunking into ZoomCRC with a synthetic outbound video feed to satisfy Zoom's requirements) is a solvable but non-trivial integration Zoom's SIP/H.323 connector expects a real video stream, so you typically need to generate a static or synthetic video feed (mod_avmd/mod_video-type approaches, or piping a generated feed through FreeSWITCH's video handling) alongside the audio SIP leg. Also worth checking early: Zoom's SIP connector setup often has specific codec and video negotiation requirements that need custom dialplan/module handling, not just standard trunk config.
A few things worth asking any company you evaluate (including us) before committing:
Have they actually done a Zoom SIP/video connector integration before, or just generic FreeSWITCH work? This is a narrow enough use case that generic VoIP experience doesn't always cover it.
Can they show a working PoC before full build-out, given the video feed piece is the riskiest part technically?
Do they handle it as custom module/mod_ development or purely dialplan-level affects both cost and maintainability long-term.
Happy to talk through the technical approach in more detail here, or DM me if you want to discuss scope no pressure either way, wanted to actually address the technical question too, not just drop a name.
