I am trying to use DNS SRV records to get the proxy addresses. We have the SRV records created and can see that the SPA8000 is getting them via a packet trace but when I make a call the DNS SRV domain gets sent in the invite and not the proxy address. Then invite gets sent to the correct proxy host but the invite is in an invalid format or something and I get a 400 bad request from the proxy server.
I'm not using the default SRV record name so my proxy looks like this in the SPA. _sip_dns1._udp.domain.com.
Use DNS SRV: Yes
DNS SRV Auto Prefix: No
The invite looks like this INVITE sip:19495551234@_sip_LO0c._udp.domain.com SIP/2.0
Is there a way to send the call with the IP of the proxy server, or something else, in the invite?
