I have found something in the opensips.log that might shed some light:
extracted routes [<sip:184.108.40.206;lr>,<sip:qa7vqblfc1c] , ct  and bind
Dec 14 16:17:00 qa7vqsbc4.qa7.vocal-qa.com /usr/sbin/opensips:
ERROR:core:parse_nameaddr: no > found
I also see this when initially doing the topology hiding:
Trying to propagate username [blf]
/usr/sbin/opensips: DBG:core:parse_headers: flags=ffffffffffffffff
/usr/sbin/opensips: DBG:core:print_rr_body: current rr is <sip:
/usr/sbin/opensips: DBG:core:print_rr_body: current rr is
/usr/sbin/opensips: DBG:core:print_rr_body: out rr
