A nice Open Source PBX/VoIP package that fits in every business **Rating:** 5.0/5.0 stars **Reviewed by:** Jorge Carlos F. | Expert System Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 23, 2020 **What do you like best about Asterisk?** Modular, easy to integrate, Open Source. With a little effort you can improve the phone communications in SOHO or medium company, one of the strengths of Asterisk is the ability of build a heterogeneous system. You can use PCI or PCIe telephony interfaces or media gateways (Patton, Grand Stream, etc.) to connect your PBX to the landline or cell network. Also you can choose between some Asterisk based distributions (can be downloaded in ISO format) in order to install a dedicated system with a rich web interface in order to configure the PBX, those are highly recommended for the first installations in order to abstract the complexity of the text based configuration. Obviously it gives the opportunity to build complex systems/architectures but as all the other things it require several years of experience. **What do you dislike about Asterisk?** The first approach isn't very easy, but as all the new things. After reading the documentation you can get the work done. On the other hand I can't find other points to dislike, within the years of Asterisk user I've never found a headache situation regarding the operations of the PBX built with Asterisk. For this reason I recommend it to those that are searching the workhorse of their telephony system project. **Recommendations to others considering Asterisk:** Is a very convenient solution with many possibilities to improve the communications of your business **What problems is Asterisk solving and how is that benefiting you?** Using the Asterisk PBX we've solved some complexities with a very convenient investment (not only the time). ### 13.

New features are being added all the time. **What do you dislike about Asterisk?** As with any software you will run into bugs. Over the last five years I have run into three issues.

The open source backbone of SMB communications **Rating:** 5.0/5.0 stars **Reviewed by:** William F. | Chief Operating Officer, Internet, Small-Business (50 or fewer emp.) **Reviewed Date:** October 03, 2017 **What do you like best about Asterisk?** Asterisk is flexible. It can do nearly anything you need in regards to communication. Need to send an SMS text? Asterisk has a module that can do that. Need to interface with a really old phone system to make it interop with new SIP technologies? Asterisk can do this as well. It can provide the backbone of nearly any business or personal communication you need to make. **What do you dislike about Asterisk?** As backbones go, it is very robust, but to truly take advantage of most of it's flexibility you need to be able to provide code in the form of PHP for the AGI interface or dialplan on the config files. This can get convoluted since there are few resources online to tech yourself how to code AGI or write dialplans. **Recommendations to others considering Asterisk:** Asterisk is the core of a communications solution, but it is just as important to find a good interface for Asterisk. The most popular is FreePBX, but there are many other interfaces that can be more efficient depending on your needs. **What problems is Asterisk solving and how is that benefiting you?** Asterisk is the core of our business phone system. But it also serves a larger role in our communications networks for our customers as well. From providing dialtone for customers to offering conference calling platforms for business use, Asterisk solves most communication problems. ### 48.

The true value of Asterisk **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.) **Reviewed Date:** November 20, 2017 **What do you like best about Asterisk?** The reliability and the versatility of the platform. **What do you dislike about Asterisk?** Not much really given that one has to be fully committed to fully understanding the platform and how to use it before actually exploiting the full power it can bring to your business. **Recommendations to others considering Asterisk:** As an end user, or a provider, you must be committed to the platform and acquire or develop expertise in-house to properly make use of it. However, once this commitment is made, the rewards can flow interminably. We would never consider an alternative at this point. **What problems is Asterisk solving and how is that benefiting you?** Asterisk is at the core of our product suite. We provide UCaaS cloud services to our customers and Asterisk serves as the engine for the telecommunications side of the business. I recall a representative, from a highly respected Session Border Controller manufacturer, once saying to me "you should consider using our extended product suite to offer cloud services. I thought about this statement and quickly replied " Asterisk provides us so much value that any alternative, specially a hardware based industry solution, would not come close to providing." That was 6 years ago. Today I am doubling down on that statement as we continue to expand our service offering while incorporating the latest Asterisk version. ### 50.
