I am taking back this issue.
Call rejected with 420 Bad Extension - Unsupported: timer
Session timer - call rejected with 420 Bad extension
And even I found another almost similar where "Emilio Panighetti-Oracle" was talking to this too

I have the same issue with the following INVITE with Require and Supported and Session-Expired Header,
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Initial INVITE:
Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY
Supported: timer, path, replaces
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Re-INVITE sip:

Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY
