RLS module in Kamailio does not support setting an outbound proxy (IIRC code is there but broken)
There was no code for support of outbound proxy address in RLS module, but was something trivial to add. I just committed the code on master branch, there is new parameter for RLS module called outbound_proxy which takes a SIP URI as address where to deliver the subscriptions.
If anyone can test, I'll backport on stable branch.
, thus, when RLS module sends SUBSCRIBE requests it always uses normal SIP resolutions mechanism to find the target address (NAPTR/SRV/A)
RLS module in Kamailio works fine for my deployments, if it is something wrong, that will be fixed if it is reported, like any bug for other pieces of code. What do you mean by "not supporting proper resource list type"?
Btw, you kept me back from some commits because you said you have some to do. Is it still valid?
Thanks, Daniel
