One way voice problem with ATA and AS5300 IOS 12.2(11T)

We use to work fine with ATA-GK-AS5300 IOS12.2(10a) but after upgarade IOS to 12.2(11T) setup of the call going well but voice always available only in one direction from AS5300 to ATA186. I'm sure that is not a codec issue because I did try four different codecs (g723, g729, g711alaw and g711ulaw) and the problem still there, however downgrade of IOS helps. So, I guess that must be a some configuration issue on AS5300 box in order to solve this problem. Please advice what that can be?

Thanking in advance,

Vladimir

What happens is that the ATA closes the logical channel soon after it is opened when interacting with gateways running 12.2.11T.

There is a DDTS opened on this issue : CSCdy36046

This is fixed in ATA version 2.16 I believe. That will solve your problem.

I would like to configure GW and keep backwards compatibility with old ATAs. Do you know how that can be done?

Thanking in advance,

Vladimir
