When we send POST request to /subscription endpoint
with this payload:
{'eventFilters': ['/restapi/v1.0/account/~/extension/~/missed-calls',
 '/restapi/v1.0/account/~/extension/~/start-ring',
 '/restapi/v1.0/account/~/extension/~/stop-ring',
 '/restapi/v1.0/account/~/extension/~/incoming-call-pickup',
 '/restapi/v1.0/account/~/extension/~/voicemail',
 '/restapi/v1.0/account/~/extension/~/message-store'],
 'deliveryMode': {'transportType': 'WebHook',
 'address': 'https://1e............315',
 'verificationToken': '75...........2e986'},
 'expiresIn': 630720000}
the address is successfully registered
but it is then visible then like:
    {

      ],

      "deliveryMode": {

      }
    }
why '~' was replaced with 2460...020 and 2744...015?
I wanted to register for a subscription of events about all phone numbers/extensions.
