Avaya IP Office “Default to IP Office Standard Mode”

Avaya has recently changed their IP Office IP500 cabinets to initially boot into the Partner/Quick/Basic Mode. This has caused some confusion in recent months as most are used to installing in the IP Office “Standard Mode”.

To avoid booting in the Partner/Quick/Basic Mode on a new system, make sure to follow these steps in IP Office Manager:

IPO standard mode

  1. Select “File”
  2. Select “Preferences”
  3. Under the “Preferences” tab, make sure “Default to Standard Mode” is checked.

This way when you log in to a new system, it will default to the IP Office “Standard Mode”.

If you already booted in the Partner/Quick/Basic Mode and want to change back to to the IP Office Standard, please follow these steps:

  1. Select “File”
  2. Select “Preferences”
  3. Select “Advanced”
  4. Select “Change Mode”
  5. Select the system you would like to change the mode and type in the user name and password.

How to Setup a T1/PRI on Switchvox

Configuring a T1/PRI circuit may seem like a daunting task, however, the Switchvox platforms make it as easy as possible.  Here is an excerpt from Digium Switchvox Knowledgebase on how to configure a T1/PRI:

Obtain Configuration Information
Before you begin configuring your T1 PRI interface in Switchvox, it is very important that you obtain all of the configuration information from your T1 provider. Throughout this document we will refer back to this information.

Installing your T1 Card

First make sure you machine is completely shut down and the power cord is removed from the machine’s power supply.

  • Make sure the correct jumper setting is selected on your card (T1 or E1)
  • Install necessary card(s) and line(s) to your PBX machine
  • Start up your PBX

Configure the Card
To start configuring your T1 card, login to the Switchvox admin section (https://your.pbx.ip/admin) and go to System Setup –> Hardware Setup. Locate the T1 card you wish to configure and click Configure. Under Configure Span Options, enter in your T1 information exactly as it is specified by your provider. Click Save Settings and after the reload click Goto Channel Admin.

Configure the Channels
T1 lines consist of 23 Bearer Channels, and 1 Data Channel (channel 24).
E1 lines consist of 30 Bearer Channels and 1 Data Channel (channel 16).

The next step is to configure the channels of your T1 card. PRI T1s have two groups, the data and bearer channels. The data channel is a single channel, most often on channel 24 that provides signaling for the PRI line. Bearer channels are the channels that you use to place phone calls. For a full voice T1, channels 1-23 are all part of the bearer group. Partial T1 lines have some subset of this group.

Data Channel
To add the data channel, click Create New Channel Group. Select a name for your group, ‘data’ is a reasonable choice. For multi-span setups, you may want to specify the span in the group name (ex. Data Channels Span 1). Under Device Type select D (Data) Channel, Secondary Device Type should be set to No signaling (PRI D channel). You can leave the Callback Extension blank.

Scroll down and check the 24th channel on the card and click Save Channel Group Settings.

Bearer Channels
Next comes the bearer channel group. Click Create New Channel Group and fill in the Group Name (ex. T1 Voice Lines or T1 Voice Lines Span 1). Under Device Type, select B (Bearer) Channel. For Secondary Device type, select from the two PRI (Primary Rate Interface) options: CPE Side or Network Side. Your T1 provider should supply you with which setting to choose, but most providers use CPE Side. The Callback Extension is the default extension to ring for incoming calls on these lines. Ask your T1 provider about your settings for the PRI Switch Type, Overlap dial, and PRI Dialplan settings. (Note: For most North American PRI providers the default settings in Switchvox should work.) Next, fill in the caller id settings that you would like to appear on outbound calls through this t1.

Lastly, check the channels that apply to this T1. For full voice T1s, check channels 1 through 23. For partial T1s, check the appropriate subset of channels. Click Create Channel Group and your T1 should now be configured. Finally, check your System Status page to make sure your newly created channels are working properly when things are hooked up.

Multi-span users
For multi-span cards, you’ll see the full consecutive listing of channels. You’ll need to create multiple channel groups accordingly. Here is an example.

Group Name: T1 Voice Lines Span 1
-choose channels 1-23
Group Name: T1 Data Line Span 1
-choose channel 24
Group Name: T1 Voice Lines Span 2
-choose channels 25-47
Group Name: T1 Data Line Span 2
-choose channel 48
and so on…

Configure Outgoing Calls
You can now go to the System Setup –> Outgoing Calls section and configure outgoing call rules to use the bearer channel group you just created.

Incoming DIDs
You can also route incoming DIDs by adding rules to the Incoming Call Routing section under System Setup –> Incoming Calls. Please refer to the DID FAQ entry for more detail.


Avaya IP Office Wireless Phone Options

Ever since Avaya discontinued their popular Avaya 3810 wireless phone, customers have been asking us: “what wireless phone options are available for my IP Office System?”

This has been a hard question to answer since most customers do not need the robust features and range that the Avaya IP-DECT and Avaya WiFi solutions carry.  While many have been wishing for an Avaya 3820 wireless phone, currently nothing is being developed yet.  Update (2/2013):  Avaya has released a new wireless phone option D100/D160

For a quick look, consider some of these wireless options currently available for your Avaya IP Office System:

  1. Avaya 3920 Cordless Phone: This can be used only on an IP Office running exclusively in “Partner” mode and requires a ETR-6 station card.
  2. Avaya/Nortel T7406e Cordless Phone: This can be used on the IP Office running both “IP Office” and “Partner” modes and requires a TCM-8 station card or expansion module. The features on the T7406e are great, but the phone requires a TCM station port, which most systems are not pre-configured with.
  3. Regular Analog Cordless Phone:  This can be used on the IP Office running both “IP Office” and “Partner” modes and requires an analog/combo station card or expansion module.   This is by far the most cost effective solution, however the feature set is minimal and the phone will act as a single line station.
  4. Avaya IP-DECT Solution (Avaya 3720, Avaya 3725, Avaya 3740, Avaya 3749): This can be used on the IP Office running in “IP Office” mode only and requires IP resources as well as appropriate licenses.  This solution is feature rich and very expandable; however, it is fairly pricey and requires some infrastructure.
  5. Avaya WiFi Phone Solution (Avaya 3641, Avaya 3645): This can be used on the IP Office running exclusively in “IP Office” mode and requires IP resources as well as appropriate licenses.  This solution is feature rich, can utilize existing WiFi networks, and is very expandable; however, is also fairly pricey and requires some infrastructure.

We know there are a great number of choices and things to consider, and we hope the recommendations listed above will help you get started.  If you have any questions or wish to go into further details regarding your specific system, please don’t hesitate to contact us at The Telecom Spot or leave a comment below.
