Overall Satisfaction with Digium Asterisk
My experience is based on several implementations that I've done with Asterisk solutions with different customers. The incredible convenience of Asterisk is to be able to create a PBX (telephone exchange) through the use of any device you are able to mount with Linux. Once configured, the PBX can easily manage all calls through VoIP devices.
- Very high ROI due to low implementation costs
- Excellent ROI due to low maintenance costs
- Line costs significantly lower than traditional lines
[Based on] my experience, we initially had to deal with Avaya PBXs, the same applies to client instrumentation (telephones, etc.). Surely we are talking about a product much more "business-like", but the management and implementation has a high cost and is not as simple as it can be (or better) with Asterisk.
An excellent scenario in which you can implement an Asterisk solution can certainly be for example a company in which you want to replace the traditional telephone line (with the consequent replacement of telephone equipment) with a VoIP line managed at home (where possible) and definitely with minor costs. Probably in large companies where the number of users is really high perhaps it is necessary to consider alternative solutions to Asterisk.
