Avaya IPO SCN and Fallback over ISDN:

To limit calls over IP Trunk in a small community network due to bandwidth and/or Fallback to PSTN in the event of WAN outage you can do the following:

1. Set the Number of outbound and voice channels to the appropriate value (can also be 0 if you want to route all calls over PSTN)
2. Set the timeout on that IP Trunk to 1 or 2 seconds
3. Create a ne ARS called **NET**
4. In that ARS, cover the extensions to the other side with a shortcode. E.g. 4XX, Dial, 004922196374NSi4411234572E, Group ID=ISDN Trunk outbound

For Avaya IP Office:

1. If you administer a User Button on a Phone (16XX and 14XX) to monitor the state of another User you can see if this one is available or busy.
You can also see, if this User is being called. If you then press that button, you´ll directly pick that call without knowing the caller Number or Name. To have that information, check the "DSS Status" in System/Telephony.

2. To have a one touch transfer of a call to a User (which is represented as a button on another users phone) add the value: Enable_OTT in the Users Sourcenumbers.

Avaya Networking SW-Release 6.2.3.x: ERS 5510, OSPF, IGMP, VLACP
Problem:

OSPF interfaces only stand in 2Way-handshake!
The ERS 5510 in the OSPF default are set to "operational mode non-5510". This can easily be verified with the command <show running-config verbose module l3-protocols>. Switch to the "config mode" and the OSPF "operational mode" on 5510 with the command set to <ip ospf op-mode 5510>. After a "Disable / Enable OSPF <no / router ospf enable / router ospf enable > the" 5510 op-mode "is then set and the OSPF interfaces change state to" full "and the OSPF routing works.

IGMP is as OSPF set in the default setting to "operational mode non-5510". This can be verified with the command <show running-config verbose module ipmc>. Switch to "config mode" and set the IGMP "operational mode" to 5510 with the command <ip igmp op-mode 5510>. Then press "yes" to confirm. Now VLACP also works!

Positioning of DECT base stations in case of increased demand in the channel:

For reasons of increased demand in the channel (through use of many handsets at one location), it may be necessary to install several base stations on a building site. In this case, make sure that the base stations have a minimum horizontal distance of 2.5 m and that the vertical distance is at least 25cm, so that the base stations do not influence each other negatively

Avaya IPO: Batchfile to save IPO Configuration.

Create a Windows.bat File with the following content:

tftp -i 172.18.44.1 get "config" ipobackup%cdate%.cfg

Let it run automatically e.g. every day and you will have the complete IPO Configuration File every day for emergency recover.

Extreme Networks Ridgeline Service Advisor

As radius server for user authentication is no longer included in the current version of Extreme Networks Ridgeline Service Advisor, here's a little tip.
The built-in Radius Server (Free radius) is tailored to the feature XNV and cannot be used for user authentication.
The radius server (Freeradius) occupies port 10559, so ports 1645 and 1812 can be used for any radius server such as IAS, etc. for user authentication on the switch.

Technical Tip August 2011:

"Did you know that you can now have individual voicemails on each SCN mode, using Distributed mode with preferred edition"

 

Technical Tip July 2011:

For Avaya IP Office:

"On IP Office version 7. If the system starts in Quick Mode out of the box, go to File-Preferences in the Manager program and in the Preferences tab, tick Default to Standard Mode.

The IP Office will then need to be defaulted. This can be performed in the Manager program by going to File- Advanced - Erase Configuration. Once these operations have been carried out, the system will revert to Standard mode after the first configuration change has been saved back to the IP Office."

 

Technical Tip June 2011:

„Avaya IPO Applications: Do not forget to run the AvayaFW.bat File after each installation of any IPO Application on any PC/Server to avoid Firewall issues."

 

Technical Tip May 2011:

IP Office Technical Tip:

"To ensure you have the best voice quality for IP Phones change the default setting in System/Telephony Tab from G.729 to G.711 during initial setup. This then negates the need to change the codec in the VoIP Extensions, which would require a reboot."

 

Technical Tip April 2011:

For Avaya IP Office CCR:

"When installing Avaya IP Office CCR please ensure that the Email addresses are configured for the Admin account and all supervisors to allow the "forgot password" option to function"

For Extreme Networks:

Stacking in XOS 12.5 - Stacking Licenses
The master of the stacks indicates the stack license. All members in the stack must have the same license. Switches that have a higher license must be limited to the stack license by using the command:
"configure stacking license-level X". In this command, the license will not be deleted. This is followed by a reboot. Switches that have a lower license must be updated to the stack license.

"When installing DECT R4 always carry out a site survey. Each base station needs to be within -70db signal strength from the next base station. A walk test can be carried out using a 3725 handset."
