I am experiencing problems with incoming calls not disconnecting. Eg, A call comes in via FXO port on my SRST Router and rings the destination extension using MGCP. However, if the call is not answered and the calling party hangs up the FXO and FXS ports do not disconnect and the telephone (IP or Analogue) keeps ringing.
I have no issues when the call is initiated from either an IP phone or the analogue extension connected to the FXS port.
Any suggestions would be appreciated.
Call Manager Ver - 220.127.116.110-13
SRST Router - Cisco 1861 (12.4(11)
MGCP Ver - 1.0
