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
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
