Issue when connecting to AstGuiClient

Hello,
I am setting up a vicidial system, and facing a problem that goes far beyond my skills. Here is a description of the problem.
Vicidial is now configured with campaigns/phones/users. Xlite correctly connects to Asterisk and can make outbound call. When trying to connect to the ASTGuiClient interface, XLite correctly receives the call. However, after accepting the call in XLite, it immediately hangs up.
It seems, after inspecting the log files, that Asterisk at this exact moment tries to call a very strange extension ("h") on the outbound PBX. As the outbound call fails, XLite gets hung up.
Can somebody help?
Thanks!
