[asterisk-dev] Ho to know the connection between 2 channels when one of them is still ringing ?

[Iñaki Baz Castillo]

I'm adding a feature to Pickup app and I need to know which channel has 
produced the second channel being rining.

Let me show an example:

200 calls 201 so there are two channels:
- channel 1)   SIP/200  -  Ring  -  Dial(SIP/201)
- channel 2)   SIP/201  -  Ringing

I've the "channel 2" structure. How could I access from it to the "channel 1" 
structure? Note that both channels are NOT bridged yet so I cannot 
use "my_chan->brigde".

Where can I find the association between both channels? Thanks.
