Hosted UC provider Telesphere announced Wednesday that it has added two new super hubs in Atlanta and Chicago to its MPLS network to expand its private SIP trunking services in the Midwest and Southeast United States.
Telesphere’s private, nationwide MPLS network already has two super PoPs in Salt Lake City and Phoenix as well as six additional PoPs in Oregon, Nevada, Arizona, Colorado, Minnesota and Pennsylvania. Two more PoPs are planned in Texas and California for later this year.
Telesphere provides direct private SIP interconnection to IP PBXs from vendors such as Asterisk, Avaya and Cisco, as well as TDM PBXs. By using Telesphere for private SIP trunking, businesses with multiple offices around the city, region or country no longer need connections to multiple service providers.
They also don't need to use PSTN gateways. Telesphere’s network uses Acme Packet session border controllers (SBCs) to enable interoperability with IP PBXs.
In addition, businesses can use Telesphere’s private SIP trunking to access cloud-based communications services. According to Telesphere, this enables businesses to use their IP PBXs but add advanced services, like video, sooner than buying more gear.
“With Telesphere’s nationwide managed network, businesses now can use private SIP trunking to extend cloud-based services such as video, fixed-mobile convergence and unified communications to all of their facilities," said Sanjay Srinivasan, Telesphere CTO.
