Klaus, Alex,
you're right. I've seen Klaus's suggestion only after writing my email message. This is the best solution and solves my problem!
regards,

Hello SR-users and -developers,
I have the question if parameters for a function in the config script (e.g. "t_relay(host, port)") in general can be set with a variable ($var(xy)). Because of having a set of SIP servers / gateways
distributed
over a wide area and therefore keeping the configuration as simple as possible, I would like to define a custom variable, assign it to a $var and use this variable as attribute for a relay function. In this case
the
variable would represent a string of an IP-address (e.g. "10.1.1.55"). When this would work I only have to adapt the custom variables on top of each config script and could let the rest "as it is".
First practical tests have shown, that the functions are NOT happy with
these "attributes". It can be used without any problems for if-else-
statements, but I fear not for functions....
The practical scenario looks like:
tc.ip11 = "10.16.65.101" desc ""; [...] route { $var(test) = $sel(cfg_get.tc.ip11); [...] if (!t_relay($var(test), "5061"))
A workaround for t_relay:
$du = "sip:"+$var(test)+":5061"; t_relay();

This configuration resulted in following error messages:
<core> [cfg.y:3326]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 413, column 18-35: syntax error
<core> [cfg.y:3326]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 413, column 18-35: call params error#012

<core> [cfg.y:3326]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 413, column 38-41: Function parameter with integer value not allowed#012
Please, could anybody clarify if this should work or not? If not - is
any
alternative possibility available for "automating" function attributes instead of re-writing each function using the same string attribute?
Thanks in advance,
Klaus
