Verizon Business  added new IP trunking capabilities aimed at easing customers’ moves from traditional TDM to voice-over-Internet-protocol (VoIP). Verizon Business said it is providing its IP trunking customers with on-demand sharing of unused trunk capacity, more platforms for IP PBX, a new path to VoIP through its Ethernet to Private IP access option, and automated rerouting of calls to maintain business continuity.
Verizon VoIP Trunking uses SIP to interoperate with either an IP or time division multiplex (TDM) PBX or key system. The interoperability provides customers the pathway to replace traditional TDM trunk lines.
Simultaneously, Verizon Business added to its managed network services with the addition of Managed IP PBX on the Nortel  IP telephony platform. The new services include on-demand networking via burstable enterprise shared trunks; additional IP PBX platform choices; Ethernet as a path to VoIP; and automatic call rerouting.
