Toshiba Announces AT&T SIP Trunking Interoperability

With SIP trunking becoming more and more popular, IP-PBX vendors are looking to provide customers with options for lower-cost trunking functionality. Recently, Toshiba announced SIP interoperability with the AT&T IP Flexible Reach service. This recent advancement solidifies Toshiba's IP-PBX offerings, giving users the opportunity to take advantage of AT&T's nationwide coverage and stability of the IP Flexible Reach service. This adds to Toshiba's portfolio of SIP interoperability certifications, including IPTimize and CBeyond. I recently had the opportunity to speak with Eric Abing, a Toshiba Telecommunication Systems product manager about the company's latest advances into the SIP trunking arena. Abing mentioned that customers can work with their respective VARs to configure and obtain SIP trunking service through the certified interoperable providers. As with any major feature upgrade, some customers using older software and processor releases may be required to upgrade their hardware and or software before SIP trunking can be enabled. In addition, customers will be required to add licensing to support VoIP trunking on their Strata CIX IP-PBX. From my perspective, this recent interoperability statement signals that the industry is moving towards VoIP, especially SIP-based trunking. Even with traditional / legacy vendors such as Toshiba, the demand for standards-based VoIP trunking is increasingly demanded from customers.
