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

"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."
"The most valuable features are call recording, call logging, and the stability."
"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."
"Highly customizable for customer needs"
"An effective, functional, very good tool for controlling resources at a low cost."
"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."
"The solution's voice services work well for our company."
"Its price is the most valuable. It is definitely one of the lowest price solutions."
"The solution is inexpensive which is its main benefit."
"IceWarp has multiple applications that are easy to use for many people."
"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."
"The solution is easy to manage and includes features such as smart documents and the archiving of user data."
 

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."
"Difficult to configure and maintain."
"The asterisk VoIP has a delay of about 400 milliseconds."
"Our customers sometimes have problems receiving mail."
"Customer service is not always helpful."
"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."
"Support should be improved. Most of the time, the queries are not resolved within the SLA."
"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."
"The database query for creating new database and querying about activities are too simplistic."
 

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."
"The license is based on the number of users."
"The solution is priced well."
"It is definitely one of the lowest price solutions."
"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."
"I would rate the pricing and eight out of ten."
"Costs far less than other solutions."
"The solution is inexpensive which is its main benefit."
"There are various licensing plans available based on geographic zone."
