I have a weird issue. After losing electricity, one of my remote Polycom, when they call or receive call, doesn't have audio for the first 5 to 30 seconds. After that, audio works and he is able to make the call. Before the electricity issue, it used to work just fine. It's been like that the for past 5 years. I've check my port forward, the settings, reset the phone, etc.

Here is the weirdest part. I was having choppy internet. I realized that Internet becomes choppy when the call doesn't work. I did a ping -t google.com. When he makes the call and he have no audio, the ping times out. When audio comes back, ping works again. If I ping a local machine, no timeout.

So it seems like the pfsense is "locking up" when the remote phone makes the call?

Really need your help on that one. On a softphone, it works without issue.

Thanks
