Abstract
In 2008, EtherSpeak certified the SureTrunkfor ShoreTel connection method to enable an innovative
“native” SIP connectivity option for ShoreTel. SIP Trunking provides the users of ShoreTel a value-
aligned alternative method for public telephone network by-pass. These connection options are enabled
when a ShoreTel customer elects to use a SIP trunking provider like EtherSpeak (using the Session
Initiation Protocol (SIP)) for communications beyond the customer‟s IP network edge.
In the current version of EtherSpeak‟s SureTrunkfor ShoreTel offering, EtherSpeak now provides the
ShoreTel administrator numerous options for connectivity of the SureTrunkfor ShoreTel service to
virtually any version of the ShoreTel system (this application note covers only ShoreTel versions 9.x
through versions 11.x).
In addition, EtherSpeak now provides options for enhancing security and quality of SIP by providing new
Quality of Service (QoS) / Class of Service (COS) guarantees by broadening the EtherSpeak solution to
include MPLS cross-connections to most Tier-One carrier data networks. This evolution is an
improvement to how the service may be delivered, and as a result, provides the ShoreTel Administrator
options for leveraging EtherSpeak SIP with seamless inter-connects to carrier networks in an
unprecedented way. New carrier supported MPLS cross-connects are available currently with AT&T /
ACC Business, Level 3 Communications, Qwest Communications, Windstream, Verizon Business and
others. Please speak with EtherSpeak sales to verify the availability of connecting to your carrier‟s
network.
They include a wide array of private wide-area-network (WAN) options (MPLS T1‟s), metro-Ethernet
connectivity, Asynchronous Transfer Mode (ATM) and whole range of quality public network broadband
and most recently, Wireless Wide Area Network (WWAN) options (including WAN (802.11n or WiMax).
In two short years, EtherSpeak SIP is steadily moving to become the de-facto standard for connecting
customer-premise based IP PBXs to carrier networks. With these options taking shape, it is an exciting
time for ShoreTel and SIP. Although SIP connectivity is a “newer” ShoreTel connection method, it is
typically regarded as less expensive, increasingly reliable, and the key driver for reducing customer
monthly recurring costs when compared to legacy Public Switched Telephone Network (PSTN)
connections. SIP is replacing Plain-Old-Telephone-Service (POTS), Basic Rate Interface (BRI), Primary
Rate Interface (PRI) or T1 / E1 trunk connections. This application note provides a guide for you in
selecting and implementing an EtherSpeak SureTrunk™ SIP connectivity option that is right for your
customer. We will help you do this by providing an understanding of the three ShoreTel Certified
methods to connect a ShoreGear system to EtherSpeak as a Communications-as-a-Service (CaaS)
provider.
1. Connecting natively to EtherSpeak over an single existing Internet connection
2. Connecting natively to EtherSpeak over a redundant Internet connection
3. Connecting natively to EtherSpeak over a private network connection
This application note is for ShoreTel customers who would like encrypted (utilizing an IPSEC VPN) SIP
trunking via a PRI handoff from the ShoreTel system.
