[asterisk-dev] LibPRI: How to add an IE to an outgoing call?

[Alexandre Cavalcante Alencar]

Hi Guys,

I am trying to enable chan_dahdi.c to selectively block ISDN reverse
charging calls (collect calls). This kind of call get identified by
the IE 74 (0x4A) when it arrives set with a new call.

I made some code to identify it and block the call as needed, but I
need to make collect calls (add IE 74 to outgoing calls) to test the
code as I am using a loop between two spans to test it.

The code I am trying to use for adding the IE 74 is here at
pastebin.ca alongside with it's generated log of one call

http://www.pastebin.ca/1395196

If someone here knows LibPRI and ISDN and can help me get this
working, I will appreciate. I don't have much experience with LibPRI
and ISDN protocol internals, and I need this hack so I can test the
code to block the collect calls, since I don't have a telco ISDN link
available.

A 'patch' to block all collect calls (not flexible)
