[Asterisk-Users] Call Transfer problem

[John Fortman]

For testing purposes, my dial line is:     Dial(${ARG2},20,tT)   When I call from one machine through asterisk to another, I can press # from either side and hear "Transfer." However, from the caller side I can continue on and put people on hold by dialing '700'.   From the callee side, I can press # but if I try to dial an extension I hear "I'm sorry.  That is not a valid extension.  Please try again."  Asterisk displays a message "Unable to find extension '7' in context ' ' "   What this tells me is that if a VOIP client picks up a line that has been Dial()ed from asterisk, that client is not given a context and, therefore, cannot dial extensions.  How can this be fixed?  Have I messed up the setup somehow?  If so, can anyone give me a working example?   John.
