[OpenSIPS-Users] Load balancer probing_method INVITE not sending contact header

[Schneur Rosenberg]

Hi, I'm using load balancer with probing_method INVITE, it worked fine
for many years with my Asterisk and Freeswitch servers, I'm migrating
my asterisk server from chan_sip to pjsip and now asterisk is
rejecting all the probing requests with a 400 Missing Contact header,
I checked the modparams for the  "load_balancer" module but couldn't
find how to have OpenSIPs add the contact header.
