Hi all, I'm using exec_dset to run a script which takes the Request-URI and returns a new Request-URI based on the number dialed. In ser.cfg I'm doing this: if (exec_dset("lookup.sh \"$SIP_RURI\"")) { # Route call } else { # Reply with a cause } Recently a customer started to use SIP-X, and his INVITES with Request-URIs looks like this: sip:1001@192.168.0.1:5060;sipx-noroute=Voicemail Ser responds with "500 Server Internal Error" to these INVITEs, which is due to that my script fails. If I run SER in the foreground with debugging I can see this: "sh: line 1: sipx-noroute=Voicemail: command not found" so clearly the ";" in the INVITE causes a problem. How do I correctly escape the SIP_RURI in my ser.cfg to prevent my script from failing? If I run my script from commandline with the request uri, everything is fine. Br, /Tobias
