Timer support on SIPREC session to SRS/NICE Recorder

Hi All

 

I would like to add a "supported: timer" to all SIPREC Session Invites going to our NICE Recorder?

 

I've tried the "options +session-timer-support" feature on the sip-interface towards the SRS but this did not change the initial INVITE out to the SRS.

 

Just adding the supported header with HMR wont help, as the session would need to work in accordance with the 

Session-Expires: 1800;refresher=uas and send keep-alive's?

 

I tried adding with a sip-feature" however I realized this wont work.

 

Any solution, to adding "timer" support on the SIPEC Session for Recording?

 

Thanks
