Module: sip-router Branch: master Commit: 4243c57511007f5af5df6d29939189925fd023da URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=4243c575...

ims_registrar_pcscf: Fallback to IP/Port/Proto search is now configurable; fallback to ip-search will be done, if no contact-header present (and the fallback is enabled).

Thanks to Camille Oudot & Hugh Waite for the improvement requests!
