hi,
i am using Voipswitch(VPS), and using Voxbone DIDs for calling card business.
i have maped DID in voxbone account,
sip:888@xx.xx.xx.xx(mysever_IP)

and i have maked an account in GW Clients for voxbone and added some IP of voxbone...

after this when i dial my DID from my Mobile/local line i get no responce from IVR or Voipswitch,
