Troubleshooting Standard 3.1
There is no dial tone when
pressing either the host call
appearance or local call
appearance keys. (continued) 6 Contact your telecom administrator.
There might be problems at the host
PBX.
A stutter is heard during a
remote dial tone. This is a normal occurrence and is caused by
the DSP activating a dial tone relay.
However, to eliminate stutter dial tone,
disable Dialtone Relay. Dialtone Relay
settings are in the Advanced Configuration
dialog box, which is available on the RLC
System Configuration Property sheet.
