Why am I not receiving the advertised 25 Mbps upload and download speeds from my Verizon FiOS service?

The variance in speed is probably because FIOS does not offer dedicated bandwidth, instead it is variable similar to DSL or cable modems, it is a basic oversubscription model. T1 circuits offer dedicated bandwidth so you are guaranteed the amount of bandwidth that you subscribe to. The cost to achieve dedicated speeds comparable to FIOS may not be feasible for most small businesses.

How can you work around the loss of Delta Server (call logging) when upgrading Avaya IP Office Software to version 7?

Two options: Implement a basic call accounting package like Veramark eCAS and gain access to various reporting functions. One of Teltek's customers invented the following: Run System Monitor with only the call log filter enabled. That will give the exact same data Delta Server used to provide. "I've left it up for 4 days now and it has no system performance hit and it creates a new log file for each day. The only issue is you can't log off the PC otherwise System Monitor goes away."

We added a new telephone number to our Avaya phone system and the other lines are not rolling over into it how do we fix this?

You will need to contact your phone service provider and request the line be added to the rollover or hunt group. When doing this you will want to review with them the specific order that the lines should roll in (i.e. 5800 rolls to 5801 to 5802, etc.).

We added a new telephone number that is part of the rollover group on our NEC phone system but don't want to publish the new phone number. We would like all of our customers calling in only on our main number.

Contact your service provider and request that all numbers in the rollover group reflect the outbound caller ID information of your main number. This way it will always appear that you are calling out on your main telephone number no matter which line you use.
