Bio

CCIE # 11225

VoIP.co.uk is a VoIP service provider operating mainly in the UK

All the normal numbering services + SIP trunks for all Cisco UC systems including UnityCM, CME and UC5XX. We love Cisco's CUBE. Our IN platform includes Contact Centre load balancing systems and simple call divert.
Recent additions to our platform include a highly secure segment supporting ONLY SIP/TLS and SRTP meaning that customers can only get this working if they're properly configured and encrypted. This was intended for Credit card merchants requiring secure PSTN termination but is proving to be in demand from everybody.
