Help: Daily "Random" Dropped Calls
Our reception desk is reporting an average of 3 dropped calls "incoming and/or outgoing" per day. The calls disconnect within 2 seconds consistently.

IP 500 V2 build 983

I used Avaya IP Office SysMonitor to log activity and told the receptionist to email me when it happens.
This is what showed up on the trace:

Very odd since that looks like an outgoing call but cause code 124 is "Answered by Other". Maybe someone else is using Call Steal or a User button. If that is the case, ensuring that the receptionists is set to Cannot Be Intruded should stop any of that.

I checked and "Cannot Be Intruded" is and has been checked.??

They are dropping both incoming calls and outgoing calls at random no real pattern or set time when it happens. The receptionist will hear a single ring on an outgoing call then it drops. On incoming dropped calls the receptionist will hear the person say hi then call drops. Again this is random but happens every day 2 or 3 times.

Also and maybe a side note.......... The receptionist did mention that at random times when an employee attempts to dial an outside line "cell phone number" ..... the call will will go directly to the receptionist instead.


Any and all help is much appreciated.

Try doing a continuous log in System Status and after it happens watch the replay. Look at the active call and see if anything is happening to it, if it's trying to forward out or if someone else is answering it. That'll usually give you a pretty good idea if it's an internal (user) issue or not.

Ok I will do this and let you know what I find.
Thanks again for your help.
