Voice problems with MC7304

Hello,

I am using a MC7304 with FW: SWI9X15C_06.03.32.04 on a telephony scenary. I turn on the system and then I make some calls. On the first calls, the sound works OK in both directions (TX and RX). But after a time the module is on, or after making some calls, the voice fails in TX direction, I mean, it seems the PCM interface of the module stop to take the frames transmitted to it suddenly.

Someone know something about this problem?

Thanks
