[Users] rewritehost failure route

[Cseke Tamas]

Hello,

I 've problem with rewritehost function in failure_route with openser 1.1.0

In core functions i don't know in which route can i use them, unlike 
functions in modules.

I 'd like to make a failover system,

In route block rewritehost is successfull but on failure route there is 
no effect i think,
i pass the host to t_relay, so it is relayed to correct host, but in 
r-uri, there is incorrect host, and sip proxy reply with (SIP/2.0 400 
Bad Request - 'Invalid IP Address)


route{
......
   
                t_on_failure("1");
                rewritehost("xxx.xxx.xxx.90");
                t_relay();
.....
}

failure_route[1] {

    t_on_failure("2");
    append_branch();
    rewritehost("xxx.xxx.xxx.91");
    t_relay("xxx.xxx.xxx.91");
}


failure_route[2] {
    # failover cisco (zajcek)
    append_branch();
    rewritehost("xxx.xxx.xxx.31");
    t_relay("xxx.xxx.xxx.31");
}

Thanks any help,
Tamas
