[Freeswitch-users] Route calls based on the Nb they are divert by

[Andreas Dröscher]

Hi everyone

I was wondering if it is possible route calls based on the numbers they were 
divert by, perhaps using "sip_redirected_by".

Let's assume I own two phone numbers of my old fixed telephone lines and one 
VoIP Account/Number. If I redirect the two fixnet numbers to the same VoIP 
number, is it possible to "demultiplex" the incoming calls based on the number 
they were redirected by?

I am not sure about the available meta data provided by SIP, however I am 
certain that my ISDN phone is sometimes showing "xxxx is calling, redirected by 
yyyyy"

Best Wishes
Andreas
