When we make calls through a high-density voice (NM-HDV-1E1-30E) module to PSTN, call setup is established, but voice does not pass through.
Our gateway is a Cisco3620 (IOS: 12.2.10) and it's connected to a PBX through the NM. The PBX can reach external phone numbers through digital and analog lines, the problem appears when we use the analog lines.
Is this a DSP problem? Any idea?
Regards.

Not enough info here. What type of signaling, wat is the topology, how does the pbx fit into the picture? What does the config look like?
