[Users] t_relay does not follow RFC3263 "Locating SIP Servers"

Hi,

I have a question regarding the behavior of t_relay.
When the proxy forwards a request for another domain using t_relay it does
not use NAPTR and SRV records of the target-domain as stated in RFC3263
"Locating SIP Servers". Instead it expects a resolvable host-name for the
domain-part or the URI.

The following example:

	INVITE sip:andrea at fenet2.at

Causes the errors:

	ERROR: mk_proxy: could not resolve hostname: "fenet2.at"
	ERROR: uri2proxy: bad host name in URI <sip:andrea at fenet2.at>
	ERROR: t_forward_nonack: failure to add branches

There are NAPTR and SRV RRs associated with domain "fenet2.at" but SER does
not use these RRs. Why?

Are there any comments on this issue?

Regards
Franz
