E1 PRI Trunks
E1 PRI trunks are supported on the ShoreGear-E1 voice switch. They are flexible
trunks that support both inbound and outbound calls for international locations.
E1 PRI trunks support:
• Inbound calls
• Outbound calls
• Caller ID number
• Caller ID name is supported for NI-2 configured trunks
• QSIG – Calling name is supported if the standard is similar to NI2. Inbound
calling name is fully supported, but outbound calling name is only supported for
Off System Extension calls
• DID
• DNIS
The ShoreGear-E1 supports PRI signaling using Euro-ISDN as well as some other
international protocols. See Appendix A, “International Planning and Installation,” for
more information.
SIP Trunks
SIP trunks are supported on the ShoreGear-120/24, ShoreGear-40/8, ShoreGear-60/12,
and voice switches. They are flexible trunks that support both inbound and outbound
calls. SIP trunks are a logical trunk end point which only takes care of SIP call control.
Media flows directly between the call initiator and the call terminator.
SIP trunks support:
• Inbound calls
• Outbound calls
• Extension, Tandem, and default destinations for inbound calls
• DID
• DNIS
By default, the "Enable SIP Info for G711 DTMF signaling" check box is off. This check
box must be enabled for ShoreTel-to-ShoreTel SIP tie trunks or for SIP devices that do
not support RFC 2833 for G711.
