[SR-Users] Get all contacts by domain

Hi, I'm running a cloud infrastructure with multiple sip domains and I have some kamailio's as registrars with dmq for usrloc replication. The kamailio registrars are configured without db, so the aors are in ram. For some gui's I need to get all aors for one sip domain, If I execute ul.dump I get all aors, but I want only a few. In my situation it would be perfect to get all registrations for one sip domain in one request (memory, performance, cache at gui...) I thought I could save the registers with save("$rd") but ul.dump doesn't allow any parameter that restricts the "location" domain. Is there any solution for this? Best regards -- Jose Fco. Irles Durá
