I have a 7400 V4.46d single cab config. that the client says the calls are dropping when on park. this doesn't happen everyday but lately they are complaining more & more. the park & hold timers are set to (0 sec.). They have 90 digital & about 100 IP phones. Of course i cant seem to duplicate the problem when im out there. im wondering if anyone else has ever seen this happen? or is there a known issue with V4.46d? thanks
