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 new 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.

Here is the log
