[OpenSIPS-Users] Drouting problem

[Brett Nemeroff]

Bogdan,I just read the docs it says:
"The module can take one optional parameter: the routing group the caller
belongs to - this may be a static numerical value or an AVP specification.
If none specified, the function will automatically try to query the dr_group
table to get this information."

I have a request. A "quick reference card" that lists, in very abbreviated
form all the module functions and parameters and the allowed values of the
parameters.. Perhaps the parameters should be listed like "C" function
declarations:

function do_routing(avp "[group id]")

or if it supported avp and/or pv:
function do_routing(avp/pv "[group id]")

Something like that. .a cheat sheet with one func per line would be really
handy (hyperlinked, even better!!) :)
