Can Cisco1750 support VoFR?

What is the IOS required to run VoFR in any of the boxes of Cisco 175x or Cisco 1760?

Re: Can Cisco1750 support VoFR?

I don't believe voice over frame-relay is supported directly on

cisco1750.

You do VOIP and voip over frame-relay with frf12 fragmentation support

for map-class but not vofr.

Correction. Voice over Frame (VoFR CISCO) is DEFINITELY supported on 1750 and 1760 platforms. You just have to run the latest IOS and one that does not have the big echo-cancellation problem on 1750s. We recommend running at least 32M DRAM on the 1750 and latest 12.2 mainline IOS or the latest 12.1.5T.

Below is documentation stating that 1750 does support VOFR:

And same for 1760:

Hope this helps.
