Full Version: DNS NAPTR not requested

I tried to configure my T28P with to use DNS NAPTR for resolving the server name. In the Account section I have set Transport to DNS NAPTR, but the phone continues to query for DNS A records. There is no A record for the hostname I set as server.
Hi Idardini,

Please set the port to 0 and check again.

If a port is set to 0 and the transport type is set to DNS-NAPTR, NAPTR and SRV queries
will be tried before falling back to A query. If no port is found through the DNS query,
5060 will be used. If an explicit port (except 0) is specified and the transport type is set
to DNS-NAPTR, the only lookup will be an A query.
