New subject: [Kamailio-Users] 403 Forbidden to SUBSCRIBE for reg-event package

2 Dec 2008

Hi,

I am getting "403 Forbidden to SUBSCRIBE" error message.

below is the scenario:

1. SCSCF is sending third party register request (with reg event) to AS.

2. AS is sending back 200 OK

3. AS is sending SUBSCRIBE (with reg event) to SCSCF.

4. scscf is sending back "403 - Forbidden to SUBSCRIBE" error message to AS.
my SIP message is inline with the specification 24.141 (section: A.7. PNA  
subscription for the reg-event package) also.

Here is my SIP message:
-----------------------
