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,
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
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
From: "External Caller" <sip:9991234@sip.myitsp.com>;tag=b99e21414928473o2
To: <sip:mailbox-deposit-url>
Call-ID: 69e9e3d9-cfcbe2bb@24.35.36.111
CSeq: 101 INVITE
Contact: <sip:9991234@24.35.36.111>
Referred-By: <sip:37683101@sip.myitsp.com>;ref=5041;mbid=7675
In the last example, the caller is directed to deposit voicemail in the mailbox ID 7675 on the
voicemail account 37683101. It further indicates that the directing station is at the internal
extension 5041. Note that it is assumed that the caller device (or the ITSP) is faithfully relayed
over the REFERRED-BY header.
The mailbox ID must be set to the extension number.
Note
The INVITE sent for an internal caller to deposit voicemail is similar, except that the FROM
header also includes a reference parameter, as shown in the following example:
INVITE sip:mailbox-deposit-url SIP/2.0
Via: SIP/2.0/UDP 172.12.244.56;branch=z9hG4bK-29752ae9
