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.

Useful for collaboration and storage but improvement is needed in API integration
The solution has traditional SSL integration, SAML, and Federation Services. In its latest version, it added SAML integration. However, it needs to work on API integration, especially for dashboards or integration with SAP for log and data system management. It doesn't yet have the kind of API that Google and Microsoft provide for synchronizing users with Active Directory. I think IceWarp needs to improve in a few areas. They have two types of admin consoles - a web-based one and a remote one. I'd like to see these combined into a single web-based admin console. The log reading and information system also needs improvement. The current way of showing incoming and outgoing logs isn't very clear. For new users, it's hard to understand these logs, especially compared to Office 365 and other systems with easier-to-read logs. They should also add an export option to get all logs with a single click whenever we need them.

Quotes from Members

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

Pros

"The most valuable features are call recording, call logging, and the stability."
"Highly customizable for customer needs"
"Best Telecommunication solution in the world."
"With the passage of time I am sure that these cons will be solved, particularly because it has added a lot savings for communication needs."
"If the client requires an economical solution with many features, we can offer them Digium Asterisk, where there is no licensing, and it is a good, economical solution."
"The most valuable feature of IceWarp is the chat rooms and file-sharing, they are useful. It is convenient that everything is in one place. You can easily share and collaborate documents, making the program's unity a significant advantage."
"IceWarp offers very extended cross-platform communication solutions."
"The TeamChat feature has been really good for our email management. It lets us collaborate, share files, and invite guests like Google Spaces or Microsoft Teams. I like the two-factor authentication for security. However, they need to improve their document collaboration tools, as their Word, Excel, and PowerPoint features are basic compared to Microsoft and Google."
"An effective, functional, very good tool for controlling resources at a low cost."
"The product is used very extensively in my company since we have around 1,500 users using it. Also, there is no requirement for any administrators to manage the product by the people who own the solution."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"It's scalable and stable."
"The groupware module is the most valuable feature."
 

Cons

"Difficult to configure and maintain."
"The asterisk VoIP has a delay of about 400 milliseconds."
"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."
"We attempted to obtain support for deleted documents through the representatives in Mumbai, but they did not have an answer for us."
"The solution should improve the mailing list feature. Google has a similar feature where you can automate sending files to different people in a sequence, but that feature is no longer available in the current version of IceWarp. Other features may also have been removed in the current version."
"The exchange compatibility mode is rather limited. Their technical support can also be better. They only provide online support, and there should be some option for escalating."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"The tool's configuration capabilities are not straightforward. Apart from that, if I want to archive emails into a vault so that they can be retrieved again later, the integration doesn't work, and IceWarp crashes."
"There are some feature improvements possible the way we use it as a hosting provider, but for most we currently have workarounds."
"The database query for creating new database and querying about activities are too simplistic."
"Support is not good and it is challenging to receive a timely response."
 

Pricing and Cost Advice

"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."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
"There are various licensing plans available based on geographic zone."
"I don't see any challenges for the Indian market. For example, 1 GB is available for around 399 INR, and 2 GB for 499 INR. They offer a range of plans, from basic to professional and enterprise, with multiple features. IceWarp's aggressive pricing is competitive compared to other market solutions like Zoho and Microsoft. One significant advantage is that IceWarp does not impose user capping like Google and Microsoft, which allows for substantial cost savings and flexibility in user conversion."
"Our licensing is on a yearly basis. There were no additional costs."
"I would rate the pricing and eight out of ten."
"The license is based on the number of users."
"The solution is inexpensive which is its main benefit."
"Costs far less than other solutions."
