Intervoice Secures New Contract with Turkcell for More Platform Capacity 

DALLAS, July 30, 2007 -Intervoice, Inc. (NASDAQ: INTV) today announced that it has secured a contract with Turkcell (NYSE:TKC; ISE: TCELL) to expand their installation of the Intervoice Media Exchange platform.  The new contract will provide additional capacity to enable the platform to host an innovative new service developed by Turkcell Technology that Turkcell has named KimAramis. KimAramis enhances the concept of missed call notification by moving it from an SMS notification only service to giving the caller the option to leave the absent subscriber a voice message as well as a text notification of the missed call. The service operates alongside the traditional voicemail service. While the expansion is only valued by Intervoice at approximately $1 million the Company is pleased to announce Turkcell's decision to expand their Media Exchange deployment.  The Company anticipates recognizing revenues on the contract during its third and fourth fiscal quarters of 2007.

"We are very pleased that we can now further realize the benefits of our investment in Intervoice and the Media Exchange platform and are delighted that Intervoice was able to work with us to develop this application for our market in exacting timescales.  We look forward to extending the scope and reach of our service on the Media Exchange platform," commented Cenk Bayrakdar; Chief Services and Product Development Officer of Turkcell.
