asterisk users - Jul 2004 - TDM400 dropping loop current 10 seconds after answer

Hi everyone,

I have a TDM400 configured with 4 FXS ports, each connected to a 
caller-id analog trunk port on a Nortel system. Outgoing calls work 
great. But on incoming calls it appears that loop current is getting 
dropped momentarily about 10 seconds after the call is answered. Since 
the Nortel system is programmed to recognize this as remote party hangup 
it is causing all incoming calls to get dropped almost immediately. 
Changing from ks to ls in * doesn't make the problem go away.  Any thoughts?

Thanks

perhaps the nortel drain too much current from the fxs card.
on the bugtracker there's a patch that allows to raise
loopcurrent on the proslic, feel free to test it.
has resolved many issues with third party devices.
