CCXML Script Receiving Messages from Web Server is not working

Hi,

I want to get all extension and corresponding phone numbers in ccxml. Hence I have created the website which responses back plain/text output required for ccxml <send>.

some how <send> is not working. the IVR is not getting connected saying 'Your call can not be completed at this time' and ccxml session gets destroyed.

Please find below the ccxml script and logs. Any help is more appreciated.

I send two parameters two web page as 'http://82.112.226.108:9095/MediaServerResponse.plaintext?Method=GetExtension&PhoneNumber=02089030278'

which responses back with

GetExtensionSuccessful
SiteExtensions=636,637,618
SitePhoneNumbers=02086340636,02086340637,02086340618

media server version is Rel_17.0_1.458.
