trying Cortelco
finding it's OK but save number, speed dial function not the best I've experienced, some minor things apparently not working. Also first phone shipped wasn't working / ringing properly. This is my 2nd

after 6 frustrating months, my problem has been resolved. It took 2 telephones,2 sets of headphones and 2 "switching thingamajigs" to go through to find the right apparatus

It is relatively easy to use, however I would have been happier if the volume control was better.

Pros and Cons
While the phone itself is satisfactory, the instruction manual is poorly written, hard to understand, and difficult to follow. I had to call tech support and they had equal difficulty in understanding the manual

New phone works well
Works well with headset. wish it had two separate voice mail buttons to go with the two lines, since each has a unique voice mail.
