Recording System Message Problem with Grandstream ATA

I ran into trouble recording my IVR greeting. I have two extensions which are identical as far as the asterix setup. One is a Grandstram HT-286, the other is a softphone. I can do the recording with the softphone, but not the HT.

In either case I call “*77”, the softphone makes a recording the HT errors out with “(macro-systemrecording, dorecord, 2) exited non-zero”.

Any ideas why?

I did notice that GSM is not one of the HT’s codecs, and is one of the softphone’s. Could that be it?
