[SR-Users] is_from_user_enum and SRV records

We have enum records where 0123456789 points to 0123456789(a)domain.tld. And then multiple SRV records pointing to the actual hosts; _sip._udp SRV record for domain.tld pointing to host1.domain.tld and host2.domain.tld for load balancing. In our config we run is_from_user_enum, which up until adding a second entry for the SRV records worked fine. Now however the is_from_user_enum lookup invariably returns the opposite DNS record for the reply. Ie. host1 is requesting and the dns cache returns host2 and then the is_from_user_enum fails and the reply is dropped. Is there a way to make is_from_user_enum test ALL values of the SRV record? Thanks! -Eric
