[asterisk-users] PRI Callerid Passthrough

[Jeff LaCoursiere]

Hey Don,

How are you?  I may be heading your way in the next month or so. Have to 
meet with a guy in Eden Prairie, and stop off at my 
brother/sisterm-in-law's as well.

Got a question for you - with TBCT, who pays for the call once it is 
transferred?  Still me as the owner of the trunk?

Lets say I take a call that was dialled locally (caller believes this is 
"free"), and I do a TBCT to an international destination, and they stay 
on the line for ten minutes.  Who gets the bill?

Cheers,

j
