TelstraClear says it is the first New Zealand-based tier 1 carrier to offer a full VoIP Interconnection service to connect its Next Generation IP Fixed Voice network with another next-gen carrier network.
TelstraClear Product Manager Drew Barr says; “WorldxChange is the first company to use TelstraClear’s SIP-based Wholesale Packet Voice Interconnect (W-PVI) that is designed to replace, over time, the legacy SS7 TDM-based linking required for existing interconnected tier 1 carriers”.
W-PVI uses Session Initiation Protocol (SIP) for signalling interconnection and Real Time Protocol (RTP) for media stream interconnection carried together over the secure TelstraClear MPLS core based IP/Ethernet network.
“W-PVI will support multiple call types including Local, National, Fixed to Mobile, and International termination and can support both voice and data convergence over a single Ethernet aggregate access,” Mr Barr says.
TelstraClear and WorldxChange have been working together for the past three months on a testing schedule and pilot programme which has resulted in a fully commercialised VoIP Interconnection Agreement between the two carriers.
Both parties have been sending and receiving live PSTN traffic over the new VoIP Interconnect links since the beginning of August.
During the testing phase TelstraClear and WorldxChange Operations staff worked together to implement a carrier-carrier IP interconnect, leading the industry into a pure IP world for voice.
“WorldxChange are leaders in VoIP interconnection, and we welcomed the opportunity to work with TelstraClear to go down the SIP Interconnect path,” WorldxChange CTO Paul Clarkin says.
“Carrier-based IP Interconnection is the future for the telecommunications industry, and we look forward to the other tier 1 carriers creating their own VoIP Interconnect products,” Mr Clarkin says.
Mr Barr says W-PVI interconnection is applicable to next-gen telcos who operate network infrastructure and have significant traffic volumes. Agreements will be negotiated individually with next-gen telcos who meet this criteria.
