[asterisk-users] How to get "Call-ID" SIP header outside "chan_sip" scope ...

[Mauro Sergio Ferreira Brasil]

Hello there!

I really hate when this happens, but...
It seems channel variable "SIPCALLID" will have the info I need, so the 
changes will be reduced to propagate the channel to ARA driver method 
"realtime_var_get".

If someone have any additional info, or can indicate some problem on 
using this variable, please let me know.

Thanks and best regards,
Mauro.
