Hi,
I have 2 sites connected through an hdlc leased line. Each site has router 1750 with one VIC - 2FXO.
Once a call is placed both FXO are stuck in the off hook state. So there is no way to make another call unless I shut down and turn on the ViC again.
I read the "famous" fxo disconnect problem file from Cisco but it didn't help.
I need to know:
1) Is this problem a bug on the FXO ports ?
2) Is this problem from the analog PBX side ?
3) How to solve this problem?
Thanks

Check your exact IOS version against bug toolkit on the TAC page to see if there is a fixed version of code available to you. Cisco should be engaged if you can't find anything there.

Hi,
you can use FXS cards......you don't have any problem......
Problem is in disconnect reason....FXO card no detect disconnect tone from PBX....
Czech firm 2N sell special "disconnect module" fot these card......
(I'm sorry for my English...:o)

I think Jan is correct. How does the FXO know to disconnect? The FXS is not going to tell it, so I think you need to figure out some sort of disconnect supervision.
