Hi All,

I've got a Cisco2801 with a call leg that is holding open a channel and causing some calls to be dropped (because the router tries to assign that channel to a call)

RT_Nelson#sh call leg ac sum

G<id> L<id> Elog A/O FAX T<sec> Codec type Peer Address IP R<ip>:<udp>

GAE4 L 13714 N ANS T0 None TELE P35486918

Total call-legs: 1

Its been there for 3 days now, we have unplugged the PRA and had the telco reset it from their end. Is there a way to kill this call leg other than recycling the router entirely?

These are typical IOS bug, only solution is to reload the router.

Thanks. I was hoping there was another way. Do you know if its been resolved in any IOS's?

Not sure, this kind of stuff comes and go, once you find a stable image better stick to it.
