Blair wrote: I'm attempting to run an existing SER config file under a recent build of sip-router. I get a syntax error on the t_on_failure("noroute") call that exists in my config file. The specific error is "bad expression: type mismatch (str instead of int)". I presume this means sip-router does not support named failure route labels. Is that correct? no, t_on_failure("xyz") can take string parameter -- actually it was always string, but converted to int in past versions. The error is in an expression like statement. Can you paste the snippet where you get the error (several lines before and after).

I'm migrating from an older version of SER to sip-router. A syntax check of my config file produces a few errors. The most confusing is : 0(27980) WARNING: <core> [cfg.y:3364]: warning in config file /home/blairs/ser-penn.cfg, line 1270, column 22-23: non constant rvalue in ip comparison Line 1270 is the following if statement: if (to_ip==$g.gw_ip && !isflagset(FLAG_PSTN_ALLOWED) && !isflagset(FLAG_TOTAG) && method != "ACK" && method != "CANCEL") I do not see anything mentioned in config_migration.txt which explains this warning. Does anyone have any thoughts on how to correct this error? Thanks,steve

If it's constant then: ip based if possible/ip, if not try string based and if that fails too try comparing with DNS(target) and if this also fails try revDNS(to_ip) with string(target). If 01.01.01.01 is the result of a non-constant expression, then no. Same as above. I guess I know now why I have left that warning :-) Andrei
