I installed and configured the latest Kamalio and all the features works except PRESENCE

Also it works with NAT clients with RTPProxy.

When I register with Jitsi or QuteCom I get 

 5(10515) ERROR: presence [publish.c:388]: No E-Tag and no body found

 6(10517) INFO: presence [notify.c:1601]: NOTIFY sip:1001@sip.abc.com via sip:1001@124.43.201.156:5060 on behalf of sip:1000@sip.abc.com for event presence

 6(10517) ERROR: presence [publish.c:388]: No E-Tag and no body found

 ERROR: presence [publish.c:388]: No E-Tag and no body found

 

Please advice me  how to fix this.

Best Regards,

Roy.
