I have a customer who would like to use a UC540 with a PRI to create the appearance of multiple businesses via mulple auto-attendants each having a separate greeting.  They would like to set up for separate DID's in the following fasion:

000-000-0001 Thank you for calling Company 1, for sales press 1, for service press 2, etc.

000-000-0002 Thank you for calling Company 2, for sales press 1, for service press 2, etc.

000-000-0003 Thank you for calling Company 3, for sales press 1, for service press 2, etc.

000-000-0004 Thank you for calling Company 4, for sales press 1, for service press 2, etc.

Q: Is this feasible with the UC540?

If not, is there some other way to accomplish this?

Yes, this is possible on the UC540. The UC540 ships with Cisco Unity Express 7.0 or later already loaded, and CUE 7.0 and later support multiple auto attendants.

You can create custom AA scripts by logging into the CUE Web GUI, and then selecting Scripts from the System menu. Select New to create a new CUE script. You can edit a CUE script that was created in the CUE Web GUI.

To add additional auto attendant extensions in CUE, you need to do the following:

  1. Set up the additional auto attendant extensions using the CUE Web GUI.
  2. Save your CUE configuration.
  3. Go into CLI and create the dial peers for the additional extensions.

Here is a sample dial peer configuration of an CUE AA extension:

dial-peer voice 2001 voip
description ** cue auto attendant number **
translation-profile outgoing PSTN_CallForwarding
destination-pattern 298
session protocol sipv2
session target ipv4:
dtmf-relay sip-notify
codec g711ulaw
no vad

Here are the rules that have to be followed for each dial peer:

  • A dial peer must be configured for each auto attendant extension
  • The dial peer tag, which follows dial-peer voice in the above configuration, must be different from that of all of the other dial peers configured on the UC520 unit
  • destination-pattern must be set to the AA extension
  • b2bua must be set on CUE Auto Attendant dial peers
  • session protocol sipv2 must be set on all CUE Auto Attendant dial peers
  • session target must be set to the CUE IP address (default setting is, unless you changed that in CLI)
  • DTMF relay must be set to sip-notify
  • G.711 mu-law must be the only codec specified for a CUE dial peer, and you should specify it by using codec g711ulaw
  • no vad needs to be set on CUE dial peers
  • You must also have inbound dial peers for numbers coming in from the ITSP or PSTN. The configuration for these dial peers is similar to those for DIDs, shared lines, and hunt groups.

Hi John,

You can do all this with CCA 2.1.   The system comes with this capability out of the box.  All you have to do is program it in the GUI.

The AA supports either a single AA with up to 3 levels, or 3 AAs each with its own (up to 12) set of actions,

Please use this as a reference...

and this is the admin guide for cca...
