SIP Trunking
Strata CIX General Description 12/07 137
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 card. The MIPU 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
cards, an update to R5.10MS17 software, 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.

• CIX Hardware: CIX40, CIX100, CIX200, and CIX670
