Re: [SR-Users] Specifying Upstream and Downstream Servers for a simple SIP proxy

Thanks very much Daniel, This is solving a part of my issue for now. Here is the routing section of my configuration file (it may be good to share it once complete as a minimally working proxy): route{ } if (!method=="REGISTER") record_route(); if (!loose_route()) { > $du = "sip:10.236.214.86:5060"; > #setdsturi("sip:10.236.214.86:5060"); #second way to do > it > if (!t_relay()) { > sl_reply_error(); > } } > } I am trying to set up a kamailio proxy on an EC2 VM using this configurations and have been running a UAC and a UAS using SIPp on two other machines (UAC <--> Kamailio Proxy <--> UAS): UAC > sipp -sn uac -nr -r 1 -rp 1000 -d 0 -l 1 -p 5060 -trace_msg -i > SELF_IP(UAC) -rsa PROXY_IP:5060 UAS_IP:5060 UAS: It looks that messages go through, and are received by the server, but what I get back at the UAC (client) is a "dead call" error: Last Error: Dead call 1-1734(a)10.140.34.188 (aborted at index 8), > receive... Is there a specific meaning to this "dead call" error? Is there anything that my proxy is missing in its routing or does it have to do with the UAC/UAS configs?
