Checking Voicemail from an External Number

The Internet voicemail service provider (IVMSP) may have an external number for their subscribers to call to check/manage their mailboxes. If this is not available, you may do one of the following:

•

•

Assign a DID number (from the ITSP).

Create a virtual extension for this purpose.

For method (a), specify a rule in the <Contact List> for the dedicated DID number. For the DID number 18005551000, this would look like the following example:

......18005551000:vmm3...

The syntax vmm<n> tells the SPA9000 to forward calls dialed to 18005551000 to the voicemail management URL on Line <n>. Because no particular mailbox is specified in this example, the caller is prompted to enter the voicemail number after the voicemail server answers. You may also specify a particular mailbox ID with this syntax (for example, vm31234).

Method (b) is used in conjunction with the Auto-Attendant. For example, you can define a single-digit extension 7 to map to the voicemail management URL on Line 4, by adding a rule to <AA Dial Plan 1> or <AA Dial Plan 2> depending on which one you are using. The rule would look like the following:

<7:vmm4>

Again, you may also specify a particular mailbox in this syntax. For information about configuring the Auto-Attendant, refer to Chapter 7, “Configuring the Auto

Attendant.”

Depositing Voicemail

An external caller can be triggered to deposit voicemail into a mailbox by sending it a REFER request during a call with <Mailbox Deposit URL> indicated in the REFER-TO header and the mailbox ID in the REFERRED-BY header. The caller device then sends INVITE to the <Mailbox Deposit URL> as shown in the example below:

INVITE sip:mailbox-deposit-url SIP/2.0

Via: SIP/2.0/UDP 24.35.36.111;branch=z9hG4bK-29752ae9
