Modem questions

Hi,

We have 6 PRI's from PSTN spread over 2x As5300, using H323
connecting
to CallManager 6.0. We then have 2x Qsig connections to a
Ericson
MD110 PBX which are MGCP controller from CallManager.

Normal calls inbound and outbound are working fine, analog
faxes
hanging off the PBX can send and receive. Problem is that we
have a
few analog modems hanging off the PBX and somehow we can not
establish
connections to them. We can hear the negotiating taking
place but no
connection gets established.

Anyone seen this before or have some ideas?

Thnx
