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?
Hi Steven,
for the term "rvalue", its somewhat described e.g. here: http://en.wikipedia.org/wiki/Value_(computer_science)
The error message probably means that the $g.gw_ip can not compared against the to_ip variable.
Do you get also this first error:
0(8530) : <core> [cfg.y:3396]: parse error in config file sip- router/test/unit/foo.cfg, line 5, column 6-10: to_ip allowed only in onsend_routes 0(8530) WARNING: <core> [cfg.y:3376]: warning in config file sip- router/test/unit/foo.cfg, line 5, column 21: non constant rvalue in ip comparison
Then i think we know the problem from the first log message. :) If you just want to compare against the To domain header, you could use the appropriate pseudo-variable or the proper select.
Cheers,
Henning
