Where the CallGlobal line fits

Your number account provides the public telephone identity, its communication controls and the SIP credentials for compatible software. Other capabilities belong to the application or phone system you choose.

Review the live product feature list before relying on an additional function. Number porting, hosted IVR, voicemail, call recording and a public customer API are not included.

Protect the line and the account

  • Keep account and SIP passwords private, including in support screenshots.
  • Confirm the active rental term before relying on incoming communication.
  • Use the complete international number and only an authorized caller identity.
