What do you like best about Asterisk?

I love that we can use asterisk to replace high cost high-cost systems completely, and there is great support online for the various issues that you may run into. Asterisk is by far one of the best examples of community-supported systems. Review collected by and hosted on G2.com.

What do you dislike about Asterisk?

Sometimes asterisk has issues that take a lot of technical expertise to fix, and sometimes those things can take a while to muddle through. Often it is better to only install security upgrades, instead of feature upgrades, to avoid breaking the system. Review collected by and hosted on G2.com.

Recommendations to others considering Asterisk:

Be sure to have an experienced asterisk expert help with the setup and have that person be on standby because when issues come up, they should be able to be dealt with quckly. Telephone problems are serious problems! Review collected by and hosted on G2.com.

What problems is Asterisk solving and how is that benefiting you?

Asterisk is a complete solution for telephony-related products. I have entirely revised many phone system issues with it, and it has texting support baked in with many installs. Review collected by and hosted on G2.com.

What do you like best about Asterisk?

its powerful, flexible and easy to integrate with various industry standard tools. Reliable and robust even under test of "1000 simultaneous calls with RTP" without compromising Calls quality! That's really great about it! It's CLI support a wide range of hardware and software tools. Review collected by and hosted on G2.com.

What do you dislike about Asterisk?

maybe on support point of view I see there should be a central database or library for user-cases so anyone can start quickly on production level, with help of this along with available wiki and documentation. Review collected by and hosted on G2.com.

Recommendations to others considering Asterisk:

Asterisk in voip world is one of the best, you should definitely check it once to know what all it can offer, as PBX, small or big phone system. with it's abilities to integrate easily with a lot of other tools and easy CLI you can achieve almost everything what any other costly standard system offers! all the best with asterisk! Review collected by and hosted on G2.com.

What problems is Asterisk solving and how is that benefiting you?

I have been using it since it's asterisk-1.6 to asterisk- 13 as PBX, sip-trunks and PRI-lines to test simultaneous RTP calls (not just signalling) that upto 1000! on my intel i7-4790 CPU @ 3.60GHz. after doing a lot of research I found this best suited for my work where asterisk does not add any significant delay or call-quality error. As an open source asterisk gives so much! Automating everything is not that tough when you become familiar with its Command line sets. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Recommendations to others considering Asterisk:

Is a very convenient solution with many possibilities to improve the communications of your business Review collected by and hosted on G2.com.

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). Review collected by and hosted on G2.com.

IDK about current documentation status. but since we have stared using it in 2005, it was terrible, but we managed to fix everything Review collected by and hosted on G2.com.

Recommendations to others considering Asterisk:

you need to use if you want to be scaleable, flrxible, and extensible! Review collected by and hosted on G2.com.

What problems is Asterisk solving and how is that benefiting you?

Probably we were the first company that started using Asterisk in production in 2005.

By 2014 we have been handling several million calls a month.

We had direct connections to mobile operators, landline operators, etc.

We had been serving short numbers like 111, 123, 911, etc.

We had been serving the Eurovision Contest as a call center.

We had been handling and billing tens of million SMS and USSD a month.

We had a vast majority of connecions with different equipment like Panasonic, LG, Nortel, etc.

We had a full zoo of different connection: PRI, FXO, FXS, SIP, H323, and a lot of written ourself to accomplish our tasks.

A lot of AGI/AMI applications.

A lot of business tasks had been solved.

Without Asterisk, we couldn't comply and fulfill all the challenges that were given to us. Review collected by and hosted on G2.com.
