asterisk users - Jun 2005 - IAX2 Max Retries dropped calls Firefly

Hi

We've recently set up and are using with success 1.0.7 using a Junghanns 
quadbri card to BRI ISDN, and Firefly with IAX2 protocol as softphones Works 
very well, however we're getting cases where sometimes the call just drops.
>From setting more verbose modes we get a log which is shown below. The
problem
seems to be the maxretries message which comes from chan_iax2. We are using 
Firefly 1.9.8 build 3945.

However I cannot work out what this message means. There is some suggestion in 
when it occurs that it might  be an IP connection issue from the softphone to 
the asterisk box. Connection is in one office via 100 M switches, very simple 
direct path. Firefly running Windows XP SP2.

We're planning to try another softphone but quite like Firefly.

Can anyone advise on this?

Thanks

Paul
