I am experiencing a strange problem for IP Phones across WAN Links.
Both end of the WAN Links are CME Routers and when a call is taking place between the two sites there is a banging background noise on the call.
I asked a test to make internal calls on each of the site like call from an IP phone to another IP Phone that is registered on the same router
and there are no issues and there is no background noise.
Can anybody advise as to what I can do to noise cancel?
Please let me know if you need any more information for this.
Many Thanks in advance,
