Advanced Topics in SPA9000 Administration Advanced Topics for SPA400 Voice Mail Service A 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 for the dedicated DID number. For the DID number 18005551000, this would look like the following example: ...|...|18005551000:vmm3|... The syntax vmm tells the SPA9000 to forward calls dialed to 18005551000 to the voicemail management URL on Line . 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 or depending on which one you are using. The rule would look like the following: 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 indicated in the REFER-TO header and the mailbox ID in the REFERRED-BY header. The caller device then sends INVITE to the 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" ;tag=b99e21414928473o2 To: Call-ID: [email protected] CSeq: 101 INVITE Contact: Referred-By: ;ref=5041;mbid=7675 SPA9000 Voice System Administration Guide 180
