If you're using libss7, you should make sure that you're configuring your signalling channel in /etc/zaptel.conf or /etc/dahdi/system.conf as mtp2 (instead of dchan). This will probably fix any problems related to high load related to realtime servicing of the link. Matthew Fredrickson Digium, Inc.
