Hi, Does anybody know how to detect whether use_media_proxy is called? What I want to do is: Do end_media_session for bye or cancel if & only if use_media_proxy has been called during invite or reply route. Is it possible? If it is then please let me know how to implement it? Thanks in advance -- Krunal Patel

Yes

You have different options: - Using a flag or branch_flag - Using an AVP - Using a Var ... I suggest you to read the docs about the nat modules, you will find examples about how to do it. Regards -- Raúl Alexis Betancor Santana

for BYEs: when you process the INVITE you can add a special parameter to record-route header that you will check in the route header of your BYE. For CANCEL, you can destroy the session in failure route and you check for nat flag or you arm that failure route for natted calls. Cheers, Daniel

Hi, For BYEs: when you process the INVITE you can add a special parameter to record-route header that you will check in the route header of your BYE. ++ I tested this. I am adding nat=yes in record-route when caller is detected behind NAT. & When processing BYE , I checked whether nat=yes does exist into Record header or not. If it does then & then do end_media_session. But if caller is having public IP then this is not working.

IF you do not need full control you can use the engage_media_proxy() function. This function monitors the dialog and handles reINVITEs and BYEs and CANCELs automatically. klaus Krunal Patel wrote:
