Mikhael - I just wanted to check in with you. Are you still experiencing this issue?  You may also want to check with your ISP.

Hi Kim,

Thanks for the reply.  We haven't had any issues yet but it's early, will keep my fingers crossed.

This reply was created from a merged topic originally titled People calling into our office have issues hearing us. Beginning yesterday, we are having issues with incoming callers being able to hear us. This is the same for all phones within our office. There seems to be certain times that we have no issues, then there will be a few hours of bad calls, and then it will go back to normal. Any ideas?

We saw the issue beginning 5/17/2016. In our case the call is answered, we can hear the caller just fine, but they can only hear bits and pieces of what we are saying.



ISP: Comcast
Location: Utah

The trace route looks good, it is reaching our server. The symptoms you mention regarding the User can hear the outside caller clean but the outside calls hears them breaking up...I recommend opening a web case so someone can work with you directly.  
  • Please verify that the port ranges are open on your firewall (port triggering) > Attach screenshot of verified open ports to case.
  • Attach screenshot of the above traceroute to case.
  • List 3 recent call samples (within 24 hours) in case: Date, Time, Called To, Called From, and result. 
  • Post case number in this thread.

One thing that we have noted, on our end users, is that whenever one sided audio occurs, it's usually due to a misconfiguration on the end users router.  The vast majority of these configurations stem around the SIP/ALG gateway settings on most modern routers.  For the softphone, especially, if the SIP/ALG is enabled, the RC calls will work occasionally, but often, the phone will ring, you will hear the client, but the client cannot hear you.

Disabling said option on the router clears the issue up immediately. Not stating that this is what is causing YOUR issue, but it is something we can have come across :)
