Cisco Cisco E-Mail Manager Unity Integration Option Dépliant

Call Progress Analysis—When you enable Call Progress Analysis for the campaign, it takes on an 
order of a half second or so to differentiate between voice and a answering machine, if the voice 
quality is good. When calling cell phones, the voice quality is quite often less than optimal so it 
might take the dialer a bit longer to differentiate.

The Unified Outbound Option provides high availability through multiple dialers per Unified CM 
cluster. Calls are distributed evenly among the dialers. If a dialer fails, the calls are re-routed to the other 
dialers throughout the enterprise that are configured to support the remaining campaign contacts. The 
calls that were in progress on the failed dialer are marked for retry.

The Campaign Manager and Import process components of the Unified Outbound Option are simplex 
components and are required to be co-located with the Logger (Side A).

It is normal practice to set up Unified IP phones to be able to fail over to another Unified CM in case of 
a Unified CM node failure in which phones are distributed across the cluster. The Dialer is not a normal 
phone, and the ports for a dialer should not be distributed across multiple nodes within the cluster. 

The dialer can tax the Unified CM node when starting a campaign or whenever resources are available 
(agents or IVR ports for transfer to IVR campaign). If two dialers are configured to share the Unified CM 
as part of distribution or node failure, a high-availability attempt can have a negative performance 
impact on the rest of the system. Each dialer has its own port throttling mechanism, and is not aware that 
another dialer may be sharing the same Unified CM. With two dialers competing, the subscriber might 
enter into a code yellow condition.

The general rule in configuring the dialers for high availability is to do no harm. As part of this guideline, 
be aware that dialers significantly affect Unified CM performance, and therefore it is advisable to 
validate the deployment design by running the resource calculators available (with appropriate login 
authentication) at

Mobiles agents are supported for outbound campaigns. However, only a nailed connection is supported.
