Hi,

 

Has anyone encountered this SIP  error message before ? 

REASON: Q.850;cause=63;text="ac95c6f7-9819-4902-b180-a15447bf0f77;Target Client has not supplied Outgoing Negotiation Request link."

We are using MS Teams/Direct routing  behind our PBX/SBC and we setup a hunt group to ring multiple users and unfortunately the call drop after couple seconds. I've done some researches but couldn't find anything related to this issue. 

Help are more than welcome !

 

Thanks

VP
