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,
