Tata Communications will be deploying the high density gateways from Sonus. This is for the international footrpint, not for the domestic Indian network. The domestic network deployment would be a much bigger opportunity if it materializes for Sonus. Sonus has been involved in trails with Tata as well as Reliance in India.

The international footprint where Sonus gets its foot inside was inherited through the VSNL acquisition. Here comes the history:

- ITXC, one of the largest VoIP ILD wholesalers, deployed multiple platforms including Excel Switching (now part of Dialogic), Huawei, Vocaltec, Cisco, Clarent (now part of Verso gone bankrupt)
- ITXC standardizes around Cisco platform, the famous AS5300
- ITXC gets acquired by Teleglobe. VoIP traffic growth remains flat for a while.
- Teleglobe gets acquired by VSNL. By this time VSNL had already been acquired by Tata I think
- VSNL also used Cisco VoIP gear in its international footprint
- Teleglobe/VSNL Intl did not migrate to high density MGX platform of Cisco
- TODAY: They announced move to Sonus platform
