Transfer Mailbox -Residence and Business -- V7.0

History Log

Product Description

A Transfer Mailbox is used when an end-user wants to transfer calls from a line that does not have Voice Messaging Service to a mailbox associated with another line.

Transfer Mailbox can only be provided to end-users with multi-line accounts and one of the following services:

Voice Messaging Service USOC(s)
Mailbox Only - Residence Only VMJXX
Voice Messaging Service - Residence Only VMJXA, VMJXB
Business Voice Messaging Service Choice VVMAD, VVMAE, VVMAF, VVMAG
Voice Mail Mailbox - Business Only MBB, MBBXA

Transfer Mailbox does not forward calls it ensures that when calls reach the Voice Response Unit (VRU) they go into the proper mailbox. In addition, a Call Forwarding feature must be added to the end-user's line to forward calls.

Transfer Mailbox allows end-users the ability to forward multiple lines into a Message Delivery Service (MDS) provisioned mailbox/router, built on the same Customer Service Record (CSR) as the Transfer Mailbox.

Transfer mailboxes may be:

  • Used on accounts with multi-lines, when the end-user wants more than one line to forward into a single, MDS provisioned mailbox/router.
  • Built on a custom ringing number when the main telephone number and the custom ringing number both forward into the mailbox.
  • Built on a Market Expansion Line® (MEL) Service, also referred to as Remote Call Forwarding, that forwards to a 1FB/1FR and then forwards to a mailbox/router. The mailbox/router needs to be MDS.

Transfer Mailboxes may not be used to associate:

  • A business account to a residence mailbox
  • A residence account to a business mailbox/router
  • A line on one CSR to a mailbox/router on another CSR
  • Associate multiple lines to a Direct Inward Dialing (DID®) mailbox/router

A forwarding feature is needed on the line with the Transfer Mailbox on it. This forwarding feature can:

  • Forward directly to the VRU
  • Forward the call to another line, which eventually forwards the call into the VRU


Transfer Mailbox is available wherever Voice Messaging Service, Voice Mail Mailbox and Business Voice Messaging Service Choice services are offered.

Additional information can be found in the Pre-Ordering Overview.
