ISCC and Call Transfer from Routing Point

Hello,

I try desperately to perform call transfer thru an URS strategy loaded on a routing point.

I succeed to do this only if call stays on the same TServer. However, I need to route the call to another TServer, especially a SIP Server, to use a Voice Platform Solution.

The problematic scenario is the following :

1/ Call arrives on PBX → TServer → URS

2/ URS routes call to SIP Server (ISCC is configured between TServer and SIP Server)

3/ SIP Server realise treatment and reroutes call to the first TServer which distribute the call to an agent

4/ Agent receives the call and transfers it via a routing point

5/ Finally, URS strategy routes the call to the external number specified in attached data

Problem : the remote phone is ringing and the call can be offhook, however, there is no one online : the first call has been cleared…

Have you any idea ?

Thanks for your help.
