It seems as though the '@' is causing the Opensips to trip over before a 
resulting packet leaves any local interface:

CRITICAL:core:mk_proxy: could not resolve hostname: "143.95.46.114as5b24544d" 
ERROR:tm:uri2proxy: bad host name in URI 
<sip:99.54.11.66;lr=on;[email protected];vsf=OTMyYjhkOTMyYjhkOTMyYjhkOTMyYjhkOTMyYjheDAMEVA-->
 
ERROR:tm:uri2su: failed create a dst proxy 
ERROR:tm:t_uac: no socket found 
ERROR:b2b_entities:b2b_send_request: failed to send request [ACK] 
ERROR:b2b_logic:b2b_logic_notify: Sending request failed - delete record

The IPs have been changed to protect the guilty.  The vsf comes from an 
upstream Opensips 1.6 instance.
