DSP fail on the PVDM-3 64

Hi all!

I have a problem in a router 3925. IOS (Version 15.0(1)M2)

This router have two PVDM-3 64, on the motherboard.

The hardware recognizes PVDMs.

All calls are being completed, but using transcoding, which was set up in these DSPs. You know this problem? Is there any way to test these PVDMs remotely? Or only physically?

What is the problem exactly ?

Hi Paolo!

When I receive calls from the PSTN, several times we can not transfer or make conferences.

Update IOS and check again.

Paolo,

Thanks for the reply.

Update the IOS is the only option in this case?
