Top three free VoIP services

Like with emails, some of us prefer to have an independent SIP address, with no relation to current job or location. Being asked several times about free services running Kamailio (OpenSER) or SIP Express Router (SER) – the recently SIP Router project, I am doing a top of my favourite free VoIP providers.

No preference among them, you have to figure out what fits the best for you alone, so I am just listing them in alphabetic order.

We had couple of interesting discussions:

– scalability – combined with MySQL track, everyone was interested in how to increase the performance and integrated better what latest MySQL offers in terms of HA and replication, good input from Henning Westerholt based on experiences with 1&1’s 2 000 000 users platform

– programmable presence server – with idea and large interest of SipWise and Andres Granig

– media services – nice talks with Olle E. Johansson and Stefan Sayer

– light b2bua – pushed on the table by Alexander Dubovikov

Probably next meeting will be the SIP-Router.org integration meeting.
