[Gkerna]

hi
im using a kamailio proxy and its dispatcher module to send sip to back end asterisk servers .
but im getting the error below on a VitalPBX ver 4 server , ive enabled “support Path” Default PJSIP Profile
VitalPBX Ver 3 running SIP for endpoints is working OK

res_pjsip_registrar.c:712 register_aor_core: Invalid modifications made to REGISTER request from ‘101’ by intervening proxy

what would this error indicate ?
