Hello,
following several requests during Kamailio World, but also in the direction of federating open source and local communities via SIP (as a result of FOSDEM panel and discussions), a SIP service was built up to be offered for free on best effort manner - the hardware and bandwidth are offered by asipto.com, the service is using the domain openrcs.com.
Main goal is to offer a free option for community members (but not restricted to) to create and use SIP accounts. The plan is to enable many (common) new features to allow people to play with, helping also to test kamailio.
There is a rather basic (and alpha stage) web portal based on wordpress+buddypress, good enough for the moment to create an account and tune some options - it is available at:
Along with voice/video calling and instant messaging, the service has enabled features such as simple presence, msrp relay, xcap server and websocket (web portal embeds a bare sip app built using jssip library). Other features will be enable over the time, but have in mind **it is a not a telephony service**, thus no such specific services like emergency, pstn interconnect, etc.
Hope it will be useful for many people - who ever wants to try it, head to https://www.openrcs.com !
Cheers, Daniel
