Hi,We use UAC module to modify FROM header (adding org tag) in the initial INVITE. The far end send us reinvite after 15 min by replacing FROM and TO field content. Therefore, otg tag will apprear in TO header in the reinvite. Kamilio ver 3.3.7 does not handle otg tag in the TO header. However, Kamilio ver 3.3.2 is working fine and can forward the TO field with otg tag without adding special character.

Hello,

Hi,

Kamailio adds extra characters in the re-invite "TO" field during session timer. There is no header manipulation in our route[WITHINDLG] block.

Re-INVITE received by Kamailio

To: sip:8131111111@?.?.?.?;otg=1;tag=1c1048632956

Re-INVITE forwarded by Kamailio To: sip:8132222222@?.?.?.?;T\033\023Z\f1;tag=1c1048632956

Your help would be greatly appreciated.

Thanks, AS
