thanks for troubleshooting. Indeed this was an issue, I did a commit to 
fix it last evening. During the times when SER and Kamailio were 
developped separately, SER added extra avp lists, in Kamailio was still 
one, corresponding to AVP_TRACK_FROM.

The commit is here, if you can give it a try and it works fine for you, 
then I will do a backport to 3.x:

If you want to read more about these AVPs lists specific to SER, then go to:
