Cisco ATA-186 Review
I have used the Cisco ATA-186 with various SIP services for a while now and can say it is a great piece of equipment that has never let me down.
Durability
It is truly amazing. I have had it up and running for a year now with no faults, reboots, resets or call drops. It simply does its job.
The device
Well, it’s ugly. OK, not as ugly as SPA-3000 by Sipura but still not as appealing as a Fritz! Box.
It has one LAN port and 2 FXS ports for connecting analogue phones. There is only one button that glows red when a call is in progress.
Configuration
The device can be configured by two ways:
(1) Handset
Just lift the handset and press the device button. You will hear the menu prompt. Then have your manual handy to dig through the various configuration codes.
This feature is very useful when you don’t have a PC nearby or need to set up initial IP settings for the device.
(2) Web interface
Can be accessed at http://<device ip>/dev and gives access to all the settings you would expect to need. But again, it’s a Cisco, so the configuration menus are aimed at the professional - expect to spend some time reading the manual. It has many advanced features to fine-tune your VoIP experience - explore them!
I would not recommend using this device with a VoIP provider directly as dial plans are pretty hard to set up and you’ll need to remember how to do it every time you need to alter them. Easypabx.com is a nice PBX intermediate.
Although the configuration might appear complex, you only need to do it once. Fantastic performance compensates for the hassle.
Cons
There are two main ones I can think of:
(1) It cannot use G711 codec on both lines at the same time.
(2) It is impossible to have telephone lines configured for two different providers, rather only for different accounts of the same provider.
Conclusion
I feel I made the right choice with this one and would recommend to anyone who is in need of a durable VoIP ATA and not afraid of some configuration challenges.

Why use an ATA when you could use a VoIP Phone? There has been a drastic cost decrease in VoIP phones that now make them as affordable as an ATA. It makes set-up easier too. |

This is a great Voip. I highly recommend it. No complaints. I learned about it from Voip Business. |
