The perfect option for customers of all sizes, SureTrunk offers an unparalleled features and benefits list

EtherSpeak’s SIP trunking solution, developed specifically for ShoreTel customers and dubbed "SureTrunk™," enables customers of all sizes (ShoreWare-based IP phone systems) to make full use of their investment by connecting SIP networks with traditional fixed-line PSTN directly.  This means ShoreTel customers can now realize all of the benefits of IP-enabled communications without any additional investments, hardware or even new firewall/gateway requirements.

The routing of SIP traffic to EtherSpeak’s SureTrunk™ service is easily set up by providing three primary categories of information

• Customer information and service option selections: Billing information, technical and functional contact information and service options selections
• Technical information: Information on customer ShoreTel technical information, LAN subnet and firewall configuration
• DID provisioning information: Customer address information for Local Inbound, Toll-free and Enhanced Local Service, Authorization for Local Number Portability (LNP)

A VPN tunnel is required to enable Shoretrunking.  The VPN tunnel provides access from the customer ShoreTel Switch IP (where trunks are configured) to a virtual IP assigned by EtherSpeak to the customer’s ShoreTel switch.  The customer’s firewall should support industry standard IPSEC encryption with availability of one-tunnel VPN license. 

ShoreTel requires licensing for SIP trunking to be enabled.  Your ShoreTel reseller can provide information on purchasing the required ShoreTel SIP trunk license.
