[cisco-voip] IP phones continue to ring after hang up

[Syed Khalid Ali]

I had the same issue, IP phones continue to ring even if the caller
disconnects the call. Read the document "FXO Disconnect Problem" at:
http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00800ae2d1.shtml

The following config solved my problem:
voice-port 0/0/0
 supervisory disconnect dualtone mid-call
 supervisory answer dualtone
 no battery-reversal
 no vad
 cptone PK
 timeouts call-disconnect 1
 timeouts wait-release 1
 timing hookflash-out 500
 connection plar opx 2221
 description ** Direct Line -- 1 **
 caller-id enable

I hope this helps!
