Hi João,

Refer to kamailio cookbooks: https://www.kamailio.org/wiki/cookbooks/4.3.x/pseudovariables

You can get source IP: $si

Try test/log most of the pseudo variables in the docs to develop better understanding.

Hello all,


I am looking for a solution to forward emergency calls inside an enterprise network.

Is there any way to forward calls based on the IP address of caller device?  

The requirement is that calls to a unique emergency number must be forwarded to specific local numbers in each building, and the IP address of the caller is the criteria for choosing the destination. A table maps IP nets to specific local numbers.

The SIP contact header has the caller IP address, but I am new to Kamailio and I am not sure where to start. Any suggestions?


Thanks in advance.

João Vitor.
