FXO not immediately disconnecting

[chris.berry.1]

Hello,

I have a client CUCME/CUE system that utilizes FXO ports for outside public lines. We are getting a fair number of "hang up" voicemails (3 seconds into the voicemail you can hear the disconnect) as the FXO ports seem to take a few extra seconds to disconnect after the caller has hung up. I'm looking for advice or solutions on fixing this.

Kind regards,

Chris

That is acceptable and within the realms of tone-based disconnection.

If you want better than that, upgrade circuits, prefeably to digital.

you need to ask on pbx side what is cptone, or try different cptones

I had that same problem using the Magic Jack to my FXO ports. Low loop current. When I switched to the Magic Jack Plus model, higher loop current, immediate disconnects. Now I have 4 Magic Jack Plus's going into my FXO ports. I hope your not using a Magic Jack...
