Lines Locking 824

[jonjoeni]

Hi chaps I know this is a minor detail but here we go. I have installed an 824 with 2 lines & 24 extensions in a school 1 year ago. There are only 2 extensions with outside line access & everybody is happy. However both lines have locked on two seperate occasions & the only resolution has been a reboot. I was thinking of exchanging the A&B legs but it is a long way away. Any ideas why this would happen the service provider states it is our problem?
Thanks
John

could they be forwarding extensions or transfering calls to external lines, if they are and there is no cpc, the lines will lock up. or if they havevoicemail/AA could cause this problem if a call is transfered and not answered.

Other thing could be power issues, you could try a UPS

Thanks obtsystems. I have not enabled forward/transfer to CO disabled by default so cannot see this happening. I will get a hold of a surge protector & see if that makes a difference. The customer would like a UPS but only at my expense (this is your problem).
Thanks

A surge plug will not do. and it is his problem if his power is not stable.

if you had one put it on to prove it is causing the problem,
letting him know that unstable power is not a system fault and if it sorts it out he will have to buy it or put up with resetting the system.
