Hi Friends,
If anyone has suggestions, I would appreciate your help. I have configured an MGCP gateway with an FXS port for a Polycom conferencing station. Everything is working as expected except for 1 issue. If the Polycom initiates a call and hangs up first, everything is fine. If the end user on the far end hangs up first, I get a new dial tone on the Polycom Station instead of it hanging up. Is there any FXS commands that I am missing?
Thanks again for your help!

By default, FXS port does "battery reversal" during call establishing/tear-down. This polarity change will cause the Polycom to falsely detect a ring.
Try configuring "no battery reversal" in the FXS port.

Thank you for the reply. I tried the command and then shut/no shut the port. Unfortunately the polycom still gives a dial tne when the far end hangs up first. Any other troubleshooting steps that I am missing? Thanks again for the help.
