SIP Trunking
Strata CIX General Description 08/14 165
SIP Trunking
SIP Trunking allows the CIX to get PRI like services from an Internet Telephony Service Provider
using Session Initiation Protocol.
Toshiba implements SIP trunking using the MIPU/GIPU card. The MIPU/GIPU is designed from
the ground up as a VoIP card able to support IP stations, Strata Net IP, and SIP trunking. With the
SIP Trunking capability of the new MIPU card, companies do not have to purchase different types
trunk cards and the bundles of physical wires to host Analog, PRI and BRI trunks. Companies are
able to leverage their existing Toshiba CIX R4.x (and later) PBX systems with just the purchase of
MIPU/GIPU cards, a software update, and corresponding license. SIP Trunking simplifies IP PBX
trunking capability by replacing all the traditional PSTN lines with one SIP Trunking device
hosted by SIP Trunking provider on the internet.
Available with the Strata CIX is Toshiba’s SIP Trunking service. Toshiba’s integrated SIP
Trunking service and equipment enable businesses to choose a single-vendor business telephone
service and equipment solution.
