3 Audience This document is intended for the SIP Trunk Customer s technical staff and Value Added Reseller (VAR) having installation and operational responsibilities Introduction This Application Note describes the configuration steps for Bell Canada SIP Trunking with ShoreTel Connect ONSITE System via Ingate SIParator/Firewall Bell Canada Bell SIP Trunking provides a gateway to the public switched telephone network through our IP network, allowing voice calls to run over a single data backbone through our core network. Bell SIP Trunking is offered over Canada s largest and most advanced MPLS network, with 70% more points of presence than the nearest competitor and our Ethernet service leveraging the industry-leading Bell fiber optic network. Offering % reliability, your business stays up and running with SIP trunking from Bell. To contact Bell Canada sales or support, please visit ShoreTel. Brilliantly simple business communications.

5 Features SIP Authentication Method This test used a Static IP Authentication method between the ShoreTel Connect Onsite PBX. SIP Authentication is required and provisioned on the Ingate. SIP Registration is not required for Bell Canada SIP Trunks. Features Supported Basic calls with G711Ulaw Call Hold and Resume Call Transfer Call Forwarding MakeMe Conference DTMF RFC 2833 Calling Party Number Presentation Calling Party Number Restricted Hunt Group Group Pickup Call Park/un-park Simul Ring Call Forward FindMe Call Recording Auto-Attendant Work Group Office Anywhere External Silent Monitor / Barge-In / Whisper Page Contact Center Conference bridge Fax G711 Pass-through Features Not Supported Fax Protocol T.38 ShoreTel. Brilliantly simple business communications. Page 5 of 42

6 Caveats and Limitations Silent Monitor/Barge-in may not work after Whisper Page due to ShoreTel defect ENG ShoreTel uses Remote Codec Honoring and will respond with same SDP for the Incoming Calls. For Outbound Calls, ShoreTel uses Codec priority as defined on the Sites Page of the ShoreTel Director. Outbound calls from ShoreTel Connect Client failed when utilizing ST-100DA as phone and trunk switch For inbound fax, if the initial codec selected as G729, the fax will fail as neither party tries to renegotiate the fax codec to G711 pass-through after the fax tone. Need to limit codec to G711 only in Ingate SIParator/Firewall as only limiting the G711 codec in ShoreTel does not work. NOTE: There may be other feature limitations when using SIP Trunks. Please refer to Chapter 19 of the ShoreTel Connect ONSITE Administration Guide for more information. ShoreTel. Brilliantly simple business communications. Page 6 of 42
