Troubleshooting: Error Codes

INFO: A special “fast-busy” tone (also called congestion tone) is

played if a temporary network problem causes a user-initiated call

action to fail. Typical call actions: making an outgoing call; picking

up a call from Manual Hold; or Group pickup. Phone users include

keyset users and mobile users logged on to the phone. The

special tone is triggered if one of the following SIP response

codes is received from the server: 606, 408 or 503.
