[Serusers] weird routing Asterisk -> ser

Ok, So i'm trying to get ser to accept calls via asterisk (which I use for my voip termination). I dialed 85283363 from asterisk, however my SER receives the call and for some reason forwards the call to 64273040757 ########################################### # in extension.conf ########################################### exten => _8.,1,Dial(SIP/max.fast.co.nz/${EXTEN},60,t) exten => _8.,2,Hangup ########################################### # in ser.cfg (i'm guessing this accepts calls with the prefix 8 ########################################### if (method == "INVITE") { if (uri =~ "sip:8[0-9].@*"){ log(1, "Forwarding to Asterisk\n"); rewritehostport("202.150.105.150:5070"); t_relay(); break; } } The sip from shows call coming from 2206, which is correct, it sees it going to 82583363, the INVITE goes to 64273040757. caller_UUID callee_UUID sip_from sip_to sip_status sip_method i_uri o_uri from_uri to_uri sip_callid username domain fromtag totag time timestamp caller_deleted callee_deleted Barry <sip:2206@voip.fast.co.nz>;tag=2604881704 <sip:85283363@voip.fast.co.nz>;tag=0011219c488307c... 200 INVITE sip:85283363@voip.fast.co.nz sip:64273040757@voip.fast.co.nz sip:2206@voip.fast.co.nz sip:85283363@voip.fast.co.nz 5E6EFD0E-A920-412B-B760-C7F29E96E7AC(a)10.200.3.173 2206 voip.fast.co.nz 2604881704 0011219c488307ca4af6c9fb-0b9b8c1b 2005-04-04 01:13:59 20050404131359 0 0
