[OpenSIPS-Users] B2B module and CANCEL

[Denis Putyato]

Hello

 

I found that this problem appears when I use append_hf() to add some header in local route of the proxy1 before sending INVITE to proxy2. Without this adding problem disappears.

Hello!

 

I have a such problem opensips1.6.4-2

 

There are two proxies of version 1.6.4.-2 which has been installed on the same server.

 

One proxy (proxy1) using B2B “top hiding” and located in /usr/local/sbc and using one signaling port 

Another proxy (proxy2) is just SIP proxy and located in /usr/local/opensips1.6.4/ and using another signaling port

 

Both proxies using the same ip address of the server

 

Call flow:

 

some UA – proxy1 – proxy2 – some gateway

 

When UA generate CANCEL then proxy1 does some strange things with FROM or TO uri headers (you can see it in attachment).  Because of this proxy2 cannot parse CANCEL properly and transaction in proxy2 cannot be canceled.

 

Thank you for any help.
