<tt>Hi Duane,<br>
<br>
If the SIP URI has no proto + port indication, first, a NAPTR
record should be looked up for finding the supported protocols.
So, if TCP and TLS only are supported (and advertised via SRV),
the domain should publish a NAPTR record pointing to TCP and TLS
protos.<br>
<br>
Regards,<br>

<div text="#000000" bgcolor="#FFFFFF"> OpenSIPS follows
RFC3263, see sip_resolvehost() in resolve.c for more
details. If you send a a request that is not a sips uri,
to a plain domain with no transport parameter or port,
opensips will do a udp SRV lookup on the domain.<br>
<br>
Can you provide the actual domain please? If you cant - do
a srv lookup on it to verify it actually has an SRV.<br>

the call gets forwarded to the IP address of the

OpenSIPS default is to resolve DNS and also SRV

be because the domain is <a
