<dial>


Role: <dial> command is used when call needs to leave the system and connect with another number. For example, forwarding the call on number 1949300360 to another number 19492321402, requires system to dial another number and connect the 2nd leg with original caller. More actions can be taken if the called part does not pickup the call.

Use: 

  • Number Masking: You dont want to expose you cell phone number to your contacts. People call the DID number and that number can be forwarded to your cell phone.
  • Multiple Business Numbers: You have many numbers from different sources and want to forward all the call to your main office line.
  • Call tacking and lean generation: Have a dedicated number for each ad or landing page and forward the call to a call center. Later you can generate a report which number was called most often.
