asterisk users - Feb 2005 - Caller in meetme room quiet (low level?)

I have encountered a frustrating problem with the meetme rooms and calls 
entering the system on the Digium analog cards.

The typical scenario is:

Callers on SIP phones, X-lite, Eyebeam, Cisco 7960, IAXy
Callers entering the system from the PSTN via the digium Analog card 
(TDM400P)

In the meetme room the SIP connections can all hear each other loud and 
clear.  The PSTN people can hear everyone just fine but the SIP users 
have trouble hearing the analog PSTN connections.  The quality of the 
PSTN connections is good but the levels (volume) are low.  There seems 
to be some variability in the apparent level depending on the SIP device 
that is listening. 

The IAXy doesn't seem to have any problems with the level.

I have made some adjustments to the levels on the analog card but when i 
go to far the echo canceling converges slowly and is very annoying at 
the beginning of the call.
