Summary:                    sending or receiving faxes thru ISDN will cause the
system to slow down
Description: 
When sending and receiving faxes from chan_misd using the following cards:
- HFCPI
- Digium 4 BRI
- Beronet 2 BRI or 4 BRI

thru a linksys PAP2T FXS connected to a fax machine the entire system
collapse and CPU reach high value this is because when the call is active a
message is generated for every ISDN packet (i suppose) that flood the
asterisk and system log and also causes high disk activity.

To avoid it i temporary commented out the offending line in channel mISDN
directory and this worked as temporary fix.

Perhaps some people from chan_misdn DEV team can watch what causes this
problem.

Always reproducible.
