Hi I need to re set the number of rings on my Avaya 5410 anwerphone before it answers because it takes ages. How do I do it?

remove the power cable and put it back

You will need to go into Manager, and adjust teh voicemail timer. By default it is at 15 seconds. Figure 3.5 seconds/ring when figuring out how long you want it to ring before going to vmail.

If the number matches the CID number, you should get the name as well. But here is the hard part.
IF your system requires you to dial an access code (say 9 to get an outside line) you may have that speed dial number saved as:
913125551212

If so, the incoming caller ID would have to match exactly, meaning CID would need to show 913125551212 in order for this to work.

BUT, caller id probably only shows 13125551212, and as such, wont work.

Call a tech in. Is the phone off hook?
Is it logged in to take calls?

*00 will cancel forwarding

Do you have access to Manager? You can tag the incoming call which does not show the caller ID of a call until the call is answered.

Press the voicemail button and follow the prompts. You will need to know what the password is. When prompted for the password, try just pressing #

Make sure that you have allow analog trunk to trunk connect enabled in lines, analog options.
That will take care of your problem unless someone deleted Call forward short code

By default individual coverage is set to 45 seconds. Ask your phone vendor to reduce it.

The Voyager 510 is not a good fit for that phone. I would prefer the cs55 or awh55.

The headset will work with the phone, but will not alert you when there is a call.
