Linksys SPA941 IP Phones
So we bought some Grandstream GXP2000 IP Phones first for the office. They were fine for starting out, however as our call center grew, we found increasing issues with them - primarily with transferring calls to external Asterisk boxes. So we purchased a box of Linksys SPA941 IP Phones. These were about the same money at VOIPSupply as the Grandstream Phones. I think now the Grandstreams are a bit cheaper. However, comparing apples to oranges, Linksys has put out another great product.
Some basic features that you can expect with the Linksys SPA941:
4 Lines (or extensions)
DND (Do Not Disturb) Button
Transfer Button
Hold and Mute Button
Caller ID
Call Timer
Custom Ring Tones
2.5mm Headset Jack
And Much More!
One great thing I love about the Linksys phones are that I’m in full control. From within the Advanced GUI, I can disable buttons if I want. For example, we opted to disable the DND button. We didn’t want employees misusing the DND button, so we simply disabled it. We have enough wrapup time on the queue, to allow them to finish up a call before getting the next.
I think with our next purchase order, we’ll get the Linksys SPA942 model. It’s basically the same, but has 2 Ethernet ports, so the PC can be plugged into the phone. I’ll post about the SPA942 once we get some of those in the office.
