[Spce-user] MS Lync with SipWise

[Andrew Pogrebennyk]

Hi Chris,
you should try editing the files:
/etc/ngcp-config/templates/etc/kamailio/lb/kamailio.cfg.customtt.tt2
/etc/ngcp-config/templates/etc/kamailio/proxy/kamailio.cfg.customtt.tt2
(create them from tt2 according to handbook if they don't exit)
and add the line
modparam("rr", "enable_full_lr", 0)
in both. This should do the trick!

Regards,
Andrew
