Kani Kumar J - PeerSpot reviewer
Reliable customer communication and good third-party integrations with minor server update issues
Cisco supports third-party gadgets, including workforce management systems. These can be directly integrated with Cisco, a feature not widely supported by other contact centers. Additionally, redundancy is set up, meaning if one side of the server goes down, the other side will take over to prevent the contact center from completely failing.

AK
Call recording, call logging, and the stability are pivotal features for our clients
We mainly replace old telephony equipment. If, for instance, there is an old Alcatel telephone system (digital or analog), and the customer asks us for a new option for IP telephony, then we offer both the Cisco- and Asterisk-based systems. We know the billing, we know the pricing of the items and what we can offer with both solutions. There are multiple factors involved when selecting a vendor * stability * support * features. If the product is stable, the product has good support, and it has enough features which we can offer to our clients, then the product is under our consideration.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cisco supports third-party gadgets, including workforce management systems."
"The Click to dial feature was one of the most important features for the customer."
"We use Extension Mobility and Jabber a lot with mobile remote access. In addition to video calls with Jabber, this greatly enriched communications between coworkers."
"The most valuable features are call recording, call logging, and the stability."
 

Cons

"Some features take a lot of steps to configure, so having areas where a few clicks can configure a feature for a user would be nice."
"An improvement option could be to incorporate the Voicea solution with Communication Manager, allowing it to make a translation between different languages automatically in a conversation."
"Sometimes, minor temporary issues can arise while updating the servers."
"CTI, computer telephony integration, is a necessary component. It must be a part of the basic code. Currently, we need to use external connectors for call centers."
 

Pricing and Cost Advice

Information not available
"If the client requires an economical solution with many features, we can offer them Digium Asterisk, where there is no licensing. It is a good, economical solution."
