Could you show the received 302 from UM?
I understand that it's something as:
SIP/2.0 302 Redirection
...
Contact: <a class="moz-txt-link-rfc2396E" href="sip:other_user@10.10.2.13:5065"><sip:other_user@10.10.2.13:5065></a>;transport=TCP
Is it?
And you say that sometime the "Contact" port is 5065 and sometimes 5060? or
there are more possible values?
In case they are a fixed number of values you can do a very dirty trick:
if ( $(ct{uri.port}) == "5065" )
t_relay("tcp:10.10.2.13:5065"
else if ( $(ct{uri.port}) == "5060" )
t_relay("tcp:10.10.2.13:5060"
