Sales Director Steve Bieniek says "Swyx and VoIP Unlimited have good synergy moving forward. Our two companies already share a number of active channel partners who have deployed IP telephony solutions over the past five years. It’s good to rubber stamp the interoperability at last. Both businesses are renowned for their product innovation and we look forward to working closer with Swyx’s channel in 2011."
Channel partners benefit by having a full suite of complimentary services from VoIP Unlimited to offer such as SIP trunks, UK and International numbering services, WLR3 and CPS, Secure Broadband and Ethernet connectivity. VoIP Unlimited also provide managed billing services for channel partners not wanting to get involved in billing customers calls.
