Call Forwarding
Hi all!
I have a problem with call forwarding.
1. SD receive INVITE and send it to client.
2. Client answer with 302 Moved Temporarily and insert Contact Header into response.
3. After that SD generate new INVITE to softswitch and insert new number into request line.
So, it is a new call for softswitch but not call forwarding and it affect to billing.
I read RFC5806 about 6.1.4. Endpoint Call Forward Unconditional and I see that 302 response must contain Diversion Header with redirector number and forwarding reason. I tried to make incoming call to SJPhone with CFU and it was only Contact Header without Diversion information.
