Hi Community,
I'm a Network Engineer working with VOIP, I know some VOIP and Telco Concepts but Im not deep in VOIP so I ask for help.
I have this Topology
RT01 FXS <----> |INTERNET| <----> RT02 FXS
Both routers are Cisco IOS 12.4(20) - RT2801Routers with FXS ports
I'm having motor/flickering sound within the call degrading the voice signal, much noise.
I found this - https://bst.cloudapps.cisco.com/bugsearch/bug/CSCdw73527 but the solutions provided here didn't work, I think it's not the same situation.
Before the command no battery-reversal the call would end soon it would be off-hook
Any insight what could be generating this motor/flickering sound?
