Sorry to bump an old thread, but I felt it was appropriate to do so. When I googled "obi1062 vs obi2182", this thread came up. Posting a new thread does not seem appropriate.
I'd like to add some difference that I've noticed for anybody interested.
Pros (of OBi2182 over the OBi1062):
1. The keys on the OBi2182 are much higher quality. The best way I can describe this is telling you the issue I ran into daily on my OBi1062. Whenever I hit the keys on this phone, if I was trying to dial 123-456-7890... if I didn't concentrate on typing the keys in, I would always end up pressing one key more than once.... for example 123-4456-7890, resulting in a wrong number. Whenever I focused on typing the keys in, I'd have that same result of pressing 1 key more than once probably 1 out of 8 times. Yes, this was likely user error, but it was due to the sensitivity/quality of the keys. I do not have that issue with the OBi2182.
2. The feel of the OBi2182 has a much higher quality feel to it. It's difficult to put in words. It just feels solid and well manufactured.
Cons (of OBi2182 over the OBi1062):
1. The OBi2182 does not have the 8 keys on the right side of the phone that could be used for speed dials. Instead, you have to program them to the speed dials on the screen, which is not a big deal, but you can only program 6 on the first page, as opposed to 8. In order to accomplish this, I had to move my phone lines to the left side of the screen, which isn't an option on the OBi1062, but I never had a need on the OBi1062 either. Being right-handed, it's slightly less comfortable to select a phone line now from the left side of the screen than the right. I'm not complaining because the phone is amazing. Just highlighting this info for anybody interested in difference between the two phones.
I've had the OBi2182 for less than 24 hours at this point, so I don't have much more to report. I will "EDIT" and update this post if I come across any other items worth mentioning. So far, the OBi2182 is an excellent phone, but so is the OBi1062. I'd recommend the OBi2182 over the OBi1062 at this point simply because of the key quality and the high quality feel of the phone. That being said, the OBi1062 is still an excellent phone and anybody that owns one is going to be happy with it.
Disclaimer: I'm an end-user and have no financial stake in OBi products, services or the overall company. My only stake in them is my phone using their service.
EDIT 2019-10-08: After a few more days of use, I am still highly satisfied with the OBi2182. The overall feel of this phone is so high quality that I think about it every time I use it. As SteveInWA mentioned, the sound quality sounds exactly the same between the OBi1062 and OBi2182. I will say that I haven't put the two phones next to each other in an attempt to notice the sound quality difference, if there is any because the sound quality on both is so good that if there is any difference, I wouldn't care about it.
I will point out one issue that I've noticed and I'm not sure if it's a user error, hardware error or GV error... I'm guessing it's a hardware issue with either my phone or the headset. I will say though, my old OBi1062 had this same issue. I use a Jabra GN 9125 and OBiEHS along with the OBi1062 and OBi2182. On a guess, probably 1 out of 20 calls, when I dial out and put my headset on, there will be no audio through my ear piece. People on the other end of the line can hear me if they pick up before I notice the problem. All I have to do to get around this issue is hit the "speaker phone" button on the phone and then click back to "headset". Again, both phones do this and it doesn't bother me because it's easy to resolve, but it may bother somebody else.
