You could also put the AoR that the gateways will use to register as an attribute on the rule/carrier/gateway in DR. Then when you do the lookup you provide avps for the attributes to be provided back and you can do the lookup based on that.

And after you do do_routing() you do lookup(location). Now the tricky part is to link them, as Drouting is IP/domain driven while user location is AOR driven. So, in DR use as GW 127.0.0.1 (.2 and so on) - even if there is something phony, it has to be a valid IP. Now, after do_routing() you will have in RURI sip:DID@127.0.0.1<mailto:DID@127.0.0.1> which needs to be pushed into user location. Do transform it into a valid AOR (to be used as search key by user location), save the username part of RURI into a variable (for later restoring) and strip it -> ruri = sip:127.0.0.1 .Further use some subst/string transformation to do a static transformation from 127.0.0.N to gwN string and build AOR as sip:gwN@opensips_domain. So, in your case you will get sip:gw1@opensips_domain as an AOR that can be used for lookup location (of course, your GW must register under the AOR of sip:gw1@opensips_domain). After lookup(location) just restore the DID back into username part -> sip:DID@gw_address . Basically the trick is to get a static mapping between the phony IPs you put in DR (like 127.0.0.N) and the AORs used by the GW to register (like gwN@opensips_domain), so you can link them.

Is there any way to use registered gateway as routing destination?
