[Server-devel] [XSCE] Proposal | SIP VoIP server on XSCE

[Anish Mangal]

This looks interesting, but I would prefer to stick with SIP

Reason:
1. It is extremely scalable from running on tiny openWRT routers to big
servers
2. It is supported by a large number of free/open clients on ALL platforms.
There is also a webRTC socket for it.

The only current drawback of Kamailio right now, is there dont seem to be
ootb rpms available for arm. If there is a SIP server out there with ARM
packages, would love to test it, or otherwise - compile kamailio for ARM
