[asterisk-users] No UDPTL ports remaining

Hi all,

Lately, I've been seeing more and more instances where I get a flood of warning 
messages like this:

[Apr 26 14:09:50] WARNING[21054] udptl.c: No UDPTL ports remaining

The next thing I know, my server is dropping calls and starting to misbehave.

I use fax via T.38, so I can't just turn udptl off.  I could expand the port 
range, but I suspect that will just mask the situation.

What can I do to prevent this from happening?



Take care and have fun,
Mike Diehl.
