I have found the parking/transfer dies after about a week of operation, asterisk is very hard to stop when this ocurrs it might take up to 5-minutes to stop. After restarting asterisk everything is normal for another few days or week. So it restarts everynight per cron.
Upon restarting asterisk (Asterisk 1.4, polycom 650 w/3-sidecars + 30 IP 430) and viewing the CLI, I get these errors:
– Incoming call: Got SIP response 500 â€œInternal Server Errorâ€
