Does OpenSBC provide a complete support for DNS SRV records ?

Hello (again :-) )

In B2BUpperReg mode, does OpenSBC provide a full support for DNS SRV queries as stated in RFC 3263 ? Let me explain my case :

I would like to have to registrar for the domaine domain.me.localhost. For that purpose, My DNS has got these records for the domain me.localhost :

domain                                NAPTR   100     50      "s"     "SIP+D2U"       ""      _sip._udp.domain.me.localhost.
_sip._udp.domain                       SRV     100     1       5060    domain1
                                        SRV     200     1       5060    domain2
domain1                                A              
domain2                                A              

That says that the domain domain.me.localhost can be reached at domain1.me.localhost with the higher priority (100) and in case of non response at domain2.me.localhost

Using that record and an 'Upper Registration Route' configured as sip:@domain.me.localhost sip:domain.me.localhost:5060, everything works fine when domain1 is working. But when domain1 is not working, openSBC should reroute its calls to domain2. It looks like it does not. It still try to route the call to domain1.

Am I right ? Is is a bug ? IS it a feature not yet supported ? Please advise.
