Aastra 6757i v. 6737i compatability

We have always used Aastra 6757i phones for many years running firmware 2.6.0.2019.

I have just discovered that the 6757i is no more and it seems that the 6737i is virtually identical as far as specification goes.

Can anyone advise as to comparability between the two? Could we mix 57i and 37i phones?

Many thanks.

The two phones are functionally identical. The only obvious difference is that the 57i has 100 MB ports, and the 37i has gigabit ports.

I have used and intermixed both, even with the old Aastra scripts, and they both work fine.

Thanks for the update - useful for clients with the older models.
