FXO port not released in ISR 28XX

[Vladimiro Lerena]

Hi,

     There is a customer that is having "random" problems with FXO interfaces on a Cisco ISR 28XX, they claim that the interfaces start to get captured and cannot be release unless the do a "shut / no shut" in the port.

    boot system flash c2800nm-advipservicesk9-mz.124-15.T15.bin

     this is the port configuration:

     voice-port 0/3/0

      supervisory disconnect dualtone mid-call

      cptone AR

      timeouts call-disconnect 3

      timeouts ringing 40

      timeouts wait-release 3

      timing hookflash-out 50

      impedance complex2

      description Linea: 4303-5006

     the funny thing is that they have identical configuration on other sites, and this problem has not been detected.

thanks !

Vladimiro
