Swap of From and To - kamailio 3.1.x problem? - sr-users

24 Dec 2010

Hi

I have a problem which pops up occasionally.

My scenario is a kamailio 3.0.x server coupled with SEMS 1.2.1 Calls go
to SEMS and occasionally it will issue a refer to the caller (an SPA962
linksys)

The problem is that the refer seems to get screwed up somewhere and the
referred call changes the From field to the To field - in this case 711.
The problems start below at 15:58:21 after the refer

I'd like to know if this is a problem with Kamailio or a problem with
the phone. The call fails on the SEMS_SEND section when the From field
is validated. I suspect the phone is the culprit, but external advice
appreciated.

I'm not quite sure what the s_xxx call id means?

Here is the log
