Authenticating Options Pings

An OPTIONS ping enables a PBX to query a SIP trunking gateway regarding its supported codecs, content types, and other information without having to activate a call. 

The VoiceHost SIP Trunk cluster requires authentication on OPTIONS pings, failure to have this will result in the PBX being blocked. 

The below list shows how to do this on PBXs we have encountered with this issue:

 PBX   Version   Action
  Asterisk  13 In the PJSIP 'AOR' section:
 enable 'qualify_frequency=60'
 enable 'authenticate_qualify=yes'
