Re: [SR-Users] invalid char found in the new uri

I have a system where the calls is not disconnected properly. I get this error in syslog when receiving BYE: Jun 24 08:23:54 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:645]: restore_uri(): invalid char found in the new uri at pos 30 (#012) [sip:004540294149@127.0.0.1:507#01257441;transport=TCP;ob] Jun 24 08:23:54 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:647]: restore_uri(): this can happen when URI values are altered by end points - skipping the update Jun 24 08:23:54 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:645]: restore_uri(): invalid char found in the new uri at pos 30 (#012) [sip:004540294149@127.0.0.1:507#01257441;transport=TCP;ob] Jun 24 08:23:54 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:647]: restore_uri(): this can happen when URI values are altered by end points - skipping the update Jun 24 08:24:11 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:645]: restore_uri(): invalid char found in the new uri at pos 30 (#012) [sip:004540294149@127.0.0.1:507#01257441;transport=TCP;ob] Jun 24 08:24:11 scantronpbx /usr/local/sbin/kamailio[31588]: WARNING: uac [replace.c:647]: restore_uri(): this can happen when URI values are altered by end points - skipping the update Kamailio receives this From header: f: <sip:004540294149@194.255.22.44>;tag=e042cfe1-40f7-410d-95fd-e5bb4f8976d7;transport=TCP;ob And passes this on, where it is obvious that '%' may give a problem f: <sip:0001@192.168.2%:>;tag=e042cfe1-40f7-410d-95fd-e5bb4f8976d7;transport=TCP;ob The RR headers send forward with INVITE looks like this: Record-Route: <sip:127.0.0.1:5069;r2=on;lr=on;ftag=MYEMZIUn-UWwH-R7g9CktpyvOn1ZFuZu;vsf=AAAAAEUAcAB5AxcDGAkYCgALLjEwMQ--;did=2f6.6cc;vst=AAAAAAAABAR0AQsLGgACAW4DHA4uMC4wLjE6NTA3MA--> Record-Route: <sip:192.168.2.9:5069;r2=on;lr=on;ftag=MYEMZIUn-UWwH-R7g9CktpyvOn1ZFuZu;vsf=AAAAAEUAcAB5AxcDGAkYCgALLjEwMQ--;did=2f6.6cc;vst=AAAAAAAABAR0AQsLGgACAW4DHA4uMC4wLjE6NTA3MA--> And received on BYE Route: <sip:127.0.0.1:5069;lr;r2=on;ftag=MYEMZIUn-UWwH-R7g9CktpyvOn1ZFuZu;vsf=AAAAAEUAcAB5AxcDGAkYCgALLjEwMQ--;did=2f6.6cc;vst=AAAAAAAABAR0AQsLGgACAW4DHA4uMC4wLjE6NTA3MA--> Route: <sip:192.168.2.9:5069;lr;r2=on;ftag=MYEMZIUn-UWwH-R7g9CktpyvOn1ZFuZu;vsf=AAAAAEUAcAB5AxcDGAkYCgALLjEwMQ--;did=2f6.6cc;vst=AAAAAAAABAR0AQsLGgACAW4DHA4uMC4wLjE6NTA3MA--> RR does not seem to be the problem as mentioned here: https://opensips.org/pipermail/users/2010-October/014999.html I have attached a pcap file with the full trace. The error appears in frame 101 The setup is a bit complex, as I have 8 Kamailio's running, where 6 is identical. The first Kamailio is on port 5069, which receives a call from a door phone. It then branches the call to registrations or GSM targets, which is handled by the other Kamailio's Thus 5069 is only doing a lookup in a database and branching, plus it handles rtpengine. I first saw the error on version 4.4, and now I replicated it on 5.1.4.
