[edit] CallerID

A CallerID consists of two parts: Name and Number. The "Number" part is transferred by default by all technologies (GSM, PSTN, SIP etc), but the "Name" part is transferred only by some. The number you see on your mobile phone when someone is calling you is the "Number" part.

  • Name – the "Name" part of the CallerID.
  • Number – the "Number" part of the CallerID. Only numerical values can be entered in this field.

NOTE: if you leave these fields empty, the user can set the CallerID name by himself. Usually it is not advisable to allow the user do it on his own. If CallerID number field is empty, system will take device username as CallerID number (if device is username/password authenticated).

  • Random Number from Number Pool – This functionality gives you an ability to send different caller number on each Call. More information: Number Pool.
  • Unknown - This option lets you set CallerID number to unknown.

  • If the Provider and the Device do not have similar codecs, no call can be established.
