Avaya SBC - DNS SRV query

[crymy]

Hey,
I have installed an SBC and connected to the Provider. The provider told us that we should work with FQDN and not IP address. It seems that SBC is sending only type A, but the provider is expecting DNS SRV. The problem that I'am having is that I do not know how to configure the DNS to send DNS SRV query. I have SBC v. 6.3. I saw in a documentation from v. 6.2 that this setting was available in Routing Profile, but in v. 6.3 is not there anymore... That's why I do not get an IP address for the FQDN. Please help. Thanks a lot.

I had to do something like that once with a CUCM. Maybe just having a DNS server and the DNS SRV record for SIP for that domain in DNS is enough and the SBC will query DNS for that?

Is that something you can try?

Is not something special that I'm trying, I only want to get the IP address from the provider. I configured the DNS Server, but according to the trace that I took, is sending only DNS type A query. The provider told me that they are expecting a DNS SRV query. In this case SBC doesn't get an IP address from the provider and doesn't know where to send the SIP messages...

a solution in Avaya's knowledge base says you should uncheck next hop priority in the routing profile
