Hello,
Where does the value set in the Date header of a SIP message come from?
For some reason the time is always 2 hours behind.
A call is either initiated by a TCL script(outgoing) or the call is received by a VXML script (incoming). In both cases the Date value is 2 hours behind.
When receiving requests from our SIP provider there is no Date header present in the initial INVITE. When we send the 100 Trying back, that's when a Date header is added.
Machines:
Cisco 3925 IOS 15.2(3)T.
These are my time settings:
clock timezone GMT 1 0
clock summer-time GMT recurring last Sun Mar 2:00 last Sun Oct 2:00
ntp server 192.168.1.89
Show clock does show the correct time.
15:34:18.006 GMT Thu Aug 23 2012
Anyone have an idea how to set the Date header to the correct time? I have no way of testing this with IPPhones since we only use these machines as a voice gateway. No CME or CM installed.
Kind regards,
Grant

Hi Grant,
please contact Cisco TAC, there is nothing to do with TCL script for Date header.
Thanks,
Raghavendra
