TelTel to Support SIP Virtual Network Operators

TelTel, a provider of SIP-based global Internet telephony with presence-enabled features, is launching a program to enable ISPs, ITSPs, CLECs, carriers and other Internet service and content providers to offer SIP-based telephony and multimedia services without having to build their own SIP infrastructure.


The TelTel SIP Virtual Network Operators (SVNO) Partnership Program aims to create a "Public SIP Telephone Network" (PsipTN), a network backbone and turnkey solution operated by TelTel. Partners will be able to either provide VoIP as an independent service or an additional value-added service bundled with existing offerings by using TelTel's infrastructure.


For a one-time fee and future revenue sharing opportunities, the program includes access to the proven PsipTN platform, SIP termination and origination, a feature-rich softphone available for partner customization, full integration with the partner's existing operation and customization with legacy networks. SVNO partners will be able to deliver conferencing, voicemail and PBX features for enterprise solutions. They will also have web portals to manage their services and monitor the growth of their users.


In addition to these benefits, each SVNO partner will have the option of offering customers co-branded and remote configurable SIP equipment such as IP phones, ATA and video phones. SVNO partners who have their own network capacity may also connect the network to the SIP infrastructure by offering their own termination and origination to the PsipTN. They can still use the PsipTN's existing termination and originations for areas outside their coverage area.

Peer-to-Peer
VoIP Services Need to Take a SIP


by
Jack Chang

Peer-to-Peer VoIP services have proved to
be very popular. Skype claims to have more than 10 million users. However,
Skype and other peer-to-peer providers use proprietary technology to
deliver their services. This results in potential quality of service,
security and reliability issues, as there is no way to manage pure
peer-to-peer routing. Additionally, the ability to improve quality and
provide new services through collaboration is tough to come by in the pure
peer-to-peer environment. The limitations of peer-to-peer can be overcome
through the introduction of Session Initiation Protocol (SIP). Here
are some advantages and disadvantages to consider.
