[asterisk-ss7] chan_ss7 incoming callbycall call problems

Fri Mar 2 13:35:43 CST 2012

Define "callbycall" number. What is the callflow? 
Accepted where, by what equipment? 
Are you trying to describe something which has to do with overlap vs. enbloc
dialing in a call-through scenario with digit collection on Asterisk or is
this a one stage call where the call enters and leaves Asterisk in one go? 
By what means is this ISDN phone connected to the Asterisk machine? 
How does the dialplan look like?
