Question:
Why do I see “Waiting for Line” on my Avaya phone display when I try to make a call ?
Answer:
With SIP dial-tone (telephone service) “Waiting for Line” can mean several things.
For instance, if the number you called is busy, invalid, disconnected, not in service, all circuits are busy, etc. you will see “Waiting for Line” on your Avaya phone display. Or, if your call is rejected by any carrier along the call path for any reason, you will see “Waiting for Line” on your Avaya phone display.
With Analog or T1/PRI (traditional) telephone services, you would normally “Hear” one of the following; a busy signal, all circuits are busy message, the number you have reached has been disconnected or is no longer in service message, etc.
With SIP dial-tone (telephone service) you will see a “Waiting for Line” message on the display of your phone. You “may” not hear any of the messages stated above. In today’s telephony environment, all Carriers (dial-tone service providers) do not provide audio messages. Some Carriers send electronic signals/control information (data packets) to your IP-PBX (Avaya IP Office), and it is up to your IP-PBX to provide you with some indication that the call you are trying to make is not going to go through. If an Audio message is provided by a carrier, then your IP-PBX will pass that through, and you will “hear” the message. If not, then you will only see what your IP-PBX provides, which in the case of the Avaya IP Office, is the visual message “Waiting for Line” on your Avaya phone display.
“Waiting for Line” can also mean all of your SIP Trunks (telephone lines) are in use. We/ECS normally set up your IP Office so that if that happens, we/ECS receive an alert email from the IP Office and will notify you that an “outbound” call was rejected because all of your SIP Trunks (telephone lines) were in use at the time. (this may indicate it’s time to add an additional SIP Trunk (telephone line)
