[Freeswitch-users] Channel variables for npdi and rn on LRN dipped calls.

[Victor Chukalovskiy]

Hello and Happy New year!

A SIP call comes in that was previously dipped. I'd like to be able to 
have "rn" and "npdi" available as channel variables that I can use in 
regex expressions. Is there a way to configure FreeSWITCH to put "rn" 
and "npdi" into separate channel variable?

So far, info application shows me the following channel variables that 
contain LRN:

Caller-Destination-Number: [5551234567;npdi=yes;rn=5555550001]
variable_sip_req_user: [5551234567;npdi=yes;rn=5555550001]
variable_sip_req_uri: [5551234567;npdi=yes;rn=5555550001 at 1.2.3.4:5060]

I can probably dissect those and put "rn" and "npdi" into separate 
variables. But this means extra steps in dial-plan. In case there is a 
built-in way to accomplish the same task, it would be great!

Could you please let me know.

Thank you,
Victor
