Asterisk And Speech Server 2007 Integration

Hi,

 I am having asterisk 1.4 in my organization, now i have installed speech server 2007 for developing IVR application in .net with VXML. Speech Server 2007 supports only SIP in TCP but Asterisk Supports SIP in UDP. I need to register an extension used by speech server 2007(for application) in asterisk.

Can anyone help me to integrate Asterisk with Speech server 2007. Thanks in advance. one more thing i have tried to install OPENSER for this communication but there is no clear installation or configuration procedure.

Reply ASAP.
With Regards,
Nakesh.
