Hello,
can you check to see if the UA is sending back same values for From/To as kamailio is sending to it?
If not, then it doesn't really care for the constraint of not changing them, so you can skip auto restore of those headers. Or configure kamailio uac module to use dialog module for changing these headers instead of record routing.
Cheers, Daniel

Hi,
An INVITE with following FROM and TO headers received by Kamailio:
From: sip:+11111111111@10.10.10.10;user=phone;tag=gK006cb08b To: sip:+12222222222@20.20.20.20;user=phone
Kamailio forward it to next node with following FROM and TO headers:
From: sip:+11111111111@10.10.10.10;tag=gK006cb08b To: sip:+12222222222@20.20.20.20;user=phone
After 15 min, reINVITE for the same call received by Kamailio with following FROM and TO headers:
From: sip:12222222222@20.20.20.20;user=phone;tag=gK04c77151 To: sip:11111111111@10.10.10.10;tag=gK006cb08b
Kamailio forward reINVITE to next node with following unusual characters in TO headers
From: sip:12222222222@20.20.20.20;user=phone;tag=gK04c77151 To: sip:11111111111@10.10.10.10\000\000;user=phone;tag=gK006cb08b
I was wondering if there is a bug in Kamailio to insert these unusual characters.
Thanks,
