The perfect option for customers of all sizes, ZipTrunk offers a list of features, enabling unparalleled benefits

Dubbed "ZipTrunk™," EtherSpeak’s native SIP trunking solution was originally developed for ShoreTel customers but has now been ported over to enable Zultys-based IP PBX customers to make full use of their investment by connecting SIP networks with traditional fixed-line PSTN directly.  This means 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 ZipTrunk™ 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 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 ZipTrunking.  The VPN tunnel provides access from the customer's switch (where trunks are configured) to a virtual IP assigned by EtherSpeak.  The customer’s firewall must support industry-standard IPSEC encryption with availability of one-tunnel VPN license.
