1760 and DSP modules - PVMD-12?

[jn4181]

I am currently at a site working on a 1760 router a PVDM-256K-4 DSP module. The site needs more voice channels, I've been told that I can use PVDM-12 DSP modules from old VG2xx routers. However, Cisco's website does not show the PVDM-12 compatible with 1750. Can this be done? Thanks and sorry for double post.

You can only use pvdm-256k-xxx on the 1760.
