Create certificates for iPhone with IP Office

Some time ago I published a post that describes the new rules a certificate has to follow to be accepted by Apple’s current devices (iPhone, iPad, MacOS PCs). Besides some rules about algorithms and bit length, that are usually met by all certificate authorities, there are some requirements, you will probably not see at first view. A certificate generated later than July 1st 2019 must not be longer valid than 825 days and the certificate must contain the value “Server Authentication” (OID 1.3.6.1.5.5.7.3.1) as Extended Key Usage (EKU).

The challenge

In my last post I mentioned that the IP Office certificate authority is able to create certificates that work with iPhones and other Apple devices. That was only half the truth, because only IP Office servers (Server Edition or Application Server) on at least release 11.0.4.1 create valid certificates.

Call forwarding with Voicemail Pro

You can see Voicemail Pro kind of like a swiss army knife of an IP Office installation. Besides the common functionalities of a voicemail system and those to build automatic assistants, you have the options to read and write several user or group settings.

In this post I will describe you, how you can configure call forwarding for other users using Voicemail Pro. This can be helpful for example for assistants who have to divert the phone of the boss if needed.

Open IP Office Backup files – Part 3

In my last post I promised to show you how to use the registry to store settings and to read them. Only with that topic it would be possible to create multiple posts. I will only show you the most important options in short.

Furthermore I’ve read about using classes and created some structure in the code.

Open IP Office Backup files – Part 2

With the first post of this series I told you about my plan to create a tool, that helps you to open IP Office backup files as comfortable as possible.

In my first version of that tool I created an array, that contains three directories. The tool searches those three directories for files ending with CFG.

The structure

By it’s very nature a user doesn’t want to run a program from start to end, but wants to jump between different program parts if needed. That’s why it became clear, that I had to create a main menu to offer several options. Besides the main goal to search for backups and to open them, you will for sure want to be able to adjust some settings and even to just quit the tool.

Media Manager plays no recording

The problem

Recently I faced an interesting problem again, that I want to share with you. Should you ever have the same problem, I hope you will find this post and that you can save some time searching for the root cause. There had been a customer call, that Media Manager plays no recording.

A short look into the recordings page seemed to be fine. The system showed all made recordings. But as soon as you clicked the play button the small player window appeared. Unfortunately you couldn’t hear anything. It looked similar to the following picture with the exception that the length of the recording has been shown as zero seconds.

Open IP Office Backup files – Part 1

In most of my posts I try to have a look into several problems I faced. This can be errors or vague descriptions. But it can also be challenges, where I have to find my own solutions.

In those posts I try to document, what I learned and I hope that I can offer you some kind of value.

The idea

During my work it has been necessary several times to have a look into different IP Office backups. Either because some config changes had been done by someone else or to reuse special config ideas from one customer on another’s customer’s system. It has always been a challenge to find the correct backup at the correct location.

That is why I had the idea to build a small tool, that searches for IP Office backups below different paths and presents the result in a nice list. From that list it should then be possible to open the backup,directly.

IP500V2 Upgrade fails with HTTP error “400 Bad request”

Seite auf Deutsch öffnen

In the Tek-Tips IP Office forum I recently read about an issue with the latest update of an IP500V2 to the latest 11.0 FP4 SP1. Upgrade fails and during file transfer you can see a HTTP error message “400 Bad Request”.

User splittingcodec found the reason for the issue and posted a workaround. He found out that some files in the Manager’s MemoryCards folder are empty. The solution was to just add some content to those files. For example just use the file name as content and save the files.

IP Office Heavy load after upgrade caused by old ADI licenses

Zur deutschen Seite wechseln

The transformation

Recently we ran into an issue we didn’t figure out before.

But from the beginning… With the switch from 9.0 to 9.1 Avaya started to support the use of PLDS licenses in IP Office, even if the good old ADI licenses were still working. PLDS licenses have only been delivered dir systems with contact centers like IPOCC or ACCS. With the upgrade to 10.0 ADI licenses became obsolete and we had to migrate to PLDS licensing during the upgrade. After a few challenges with the first few license sets everything worked fine and I like PLDS.
