Hi Jason,

one reason that t_relay accept only literals is that this parameter can be 
fixed during the server startup to a "proxy" struct from the
"fixup_phostport2proxy" function. This parameter can be evaluated on runtime 
without that much overhead. If you want to replace this with an AVP, it will 
be printed and converted to a proxy for every invocation of t_relay. 

If you want to relay a message to a changing target, normally you just rewrite 
the URI and call t_relay without the destination parameter, as you surely 
know. Do you have another requirement that can't be achived this way?

If you need this functionality, and implement it in a way that don't break the 
existing t_relay, i'd would welcome a patch that change this.

Cheers,

Henning
