Hi,

I have the following issue:

 

I am using lcr module to select a gw from a set of gw's based upon R-URI prefixes. All is working fine.

 

The issue is with a CANCEL that is sent by the UAC that originates the call before a dialog can be established. This implies that the CANCEL cannot be routed to the correct GW since SER see a CANCEL and simply returns "487 request terminated".

 

How can I forward the CANCEL to the GW the the original INVITE was forwarded to?

 

Any help appreciated.....
