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

"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."
"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."
"Highly customizable for customer needs"
"The most valuable features are call recording, call logging, and the stability."
"Best Telecommunication solution in the world."
"With all of the features that are available for the users included with the license, it is reasonably priced."
"The groupware module is the most valuable feature."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
"The solution is inexpensive which is its main benefit."
"As the license of our company is very affordable per year and per user, and considering the almost-zero administration needs, I would say that the cost is returned in the first three months, compared to other solutions."
"The solution has a very good log-in to the UI when compared to other solutions."
"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."
"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."
 

Cons

"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."
"The asterisk VoIP has a delay of about 400 milliseconds."
"Difficult to configure and maintain."
"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."
"Although it is not a tool, video conferencing should be scalable and operate in a professional and efficient way."
"Support is not good and it is challenging to receive a timely response."
"Customer service is not always helpful."
"With multiple databases for VOIP, chat and web IMAP, maintenance is cumbersome."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"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."
"I would like to have a trial for mobile applications and more documentation similar to Google Drive with mobile applications."
 

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."
"Pricing and licensing is very competitive and in some cases, cheap."
"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."
"It is definitely one of the lowest price solutions."
"I would rate the pricing and eight out of ten."
"The solution is priced well."
"Price-wise, it's a cheaper solution, without a doubt. Price is the reason we are still using the tool."
