I want do this:

uaA (invite 9200001@B) ---->proxy A (invite 200001@B )--->proxyB

so in proxyA's ser.cfg:

---------------------------

if (uri=~"^sip:9[0-9]*@B") {
        strip(1);
        t_relay_to_udp( "B", "5060");
        break;
};

----------------------------

but proxyB received "sip:9200001" not "sip:200001".

please help me how can I do!

thanks.
