Automatic Daylight Savings Time Update

 The IP Office has the capacity to hold automatic daylight savings time entries for up to ten years. This may sound like a lot, but I'm starting to run into systems that have not had their automatic daylight savings times updated, and are failing to present the correct time as a result. It's easy enough to edit the entries in the list, however this can be tedious - especially if you are responsible for managing a bunch of sites. To address this, I have created a CSV file that contains the next decade of clock changes. I hope that the time change is abolished before I need to make a new one, though!

You can download the file here. Once downloaded, you need to remove the existing entries from your automatic DST settings and then import the file.


Step 1: Removing the existing entries

Log in to the IP Office using IP Office Manager. The Time Settings can be found under System --> System. Locate the drop-down box and select Delete for each entry. This may include some entries from the future, but don't worry. We will import the full decade's worth of entries. 




Once all the entries have been deleted merge the changes back to the system. From there you will need to import the CSV file you downloaded earlier. Select File --> Import/Export --> Import. This will open the Import Configuration window. The default folder will be a subfolder of your Manager folder, but I like to use a folder specific to the restoration process. In this example I will put the csv file in C:\temp and use that as my folder. Put the CSV file in place first, then select the folder.




Select the check box for Configuration. If you have followed all the steps correctly there should be no other options. Click OK to import the new time change profiles. Once imported, check in Manager to see if the profiles are there:


If everything looks right you can click OK on the System record and merge the changes. If you still need help getting the correct time set, please see my post about changing the time and date on an IP Office.


Adding a CertBot Certificate to IP Office

The IP Office generates a self-signed certificate for the purpose of presenting its identity. Any Avaya elements will trust this certificate, but modern web browsers will not by default. One option we have is to add the Avaya Certificate Authority to our list of trusted issuers, but a better way is to ensure that the IP Office presents a certificate that is universally trusted. The Electronic Frontier Foundation (EFF) is providing free publicly trusted certificates with a three month expiration. The short duration is intentional - any malicious use of the certificates wouldn't last longer than three months, making the Internet a safer place. 

The EFF has a utility called CertBot that can be used to generate these certificates on your local machine. They use Public DNS to validate that the correct machine is requesting the certificate. The whole process takes only a few minutes, and when run on a web server can automatically apply the certificates to the hosted pages.Unfortunately Avaya has not yet integrated CertBot functionality into their finished product, so we will need to manually create a certificate, extract the portion that the IP Office needs, and apply the certificate. This will need to be done on a regular basis because of the short certificate duration. Please reach out to your Avaya partner or account manager and ask them to add CertBot integration to the IP Office in future releases! As more people request this functionality Avaya becomes more likely to include it in a future software release. You can download CertBot here. We can't install CertBot directly on the IP Office, so a Linux PC or server will be required. Once CertBot is installed on your Linux PC or Server we can proceed with generating a new certificate. 

The next step is to use CertBot to create a certificate. For the purpose of this example I will redact all my screenshots, hiding the actual FQDN I used. For reference I will use the domain ipo.adventuresinvoip.ca in all of the commands. Simply change out the FQDN for the FQDN you want to assign to your IP Office. Since the CertBot utility uses DNS records you need to be sure to have a DNS A Record for the FQDN you are using. This should point to the public IP Address of the router that the Linux machine is connected to. You will need to enable port forwarding for Port 80 to the Linux machine to get CertBot to work properly since it checks for an HTTP request/response. 

My Linux machine already has a web server running, so I chose to leverage that for the generation of the certificate. To generate the certificate I ran the following command:

certbot run --domains ipo.example.ca

If you don't have a web server running on your Linux machine you can run the commmand in Certificate Only mode:

certbot certonly --domains ipo.example.ca

Once the certificate chain has been created you may be prompted to install it on your web server - since we aren't generating the certificate for this machine we should not be applying it to this server. 

Now we have a new certificate. It will be located in the CertBot folder under a subfolder for that FQDN. In our example this full path would be:

/etc/letsencrypt/live/ipo.example.ca/

The IP Office is unable to use the certificate in this format so we will need to convert it. Change to the folder containing the certificate and extract the PKCS#12 Certificate from the full chain with these commands:

cd /etc/letsencrypt/live/ipo.example.ca/
openssl pkcs12 -export -in fullchain.pem -inkey privkey.pem -out ipo.p12 -CAfile chain.pem

The second line will prompt for an export password. This password will be used to add the certificate back to the IP Office. Once complete the file ipo.p12 will be created. We can apply this certificate to the IP Office. Copy the ipo.p12 file back to your local PC and launch a web browser. The certificate is easiest to apply using Web Manager, so that's the method I will cover here. 

Log in to Web Manger using the Administrator account (other accounts can be used as long as the permissions allow the manipulation of certificates). Select Security from the top menu, then Certificates. 




This will take you to the Certificates portion of IP Office Web Manager. Here you will see a list of all the trusted certificate authorities, as well as some options to manipulate the IP Office certificate. 


The button for Set will allow us to upload our new certificate. Click Set then locate the ipo.p12 file and enter the password set during the extraction process.

The IP Office will advise you that the system and applications will stop responding while the certificate is applied. Click OK and wait for the IP Office to apply the certificate. Once applied you can view the certificate by clicking View.


Now that the IP Office is presenting the ipo.example.ca certificate to users we need to ensure that this resolves properly. We will still get an error if we try to browse to the IP Office by IP Address, since the certificate doesn't contain the internal IP. The internal DNS Server needs to point ipo.example.ca to the internal IP of the IP Office. As with many Avaya applications the IP Office performs a reverse DNS lookup to validate the FQDN. If you skip this step the IP Office will server an error page when you browse to it. Make sure that the IP Office is set to use the DNS Server that hosts your internal DNS entries. If you want your IP Office to be accessible to the Internet you can enable port forwarding on your router for ports 80, 443, 7070, 7071, and 8443. Otherwise, disable the port forwarding that was set up for the certificate creation. 

This process is a manual process that can't be automated at this time. You will need to update the certificate before it expires, following the entire process again. While this is not an ideal scenario, it is the easiest way to get free TLS certificates for your IP Office. The same process can be applied to a UC Module or Application Server - even Server Edition. Just follow the steps and remember that each element will require a unique, DNS-resolvable FQDN.

One final piece of housekeeping - the IP Office will, by default, generate an alarm when the certificate is within 60 days of expiring. To change this open the security settings, navigate to System, then Certificates. Change the Certificate Expiration Warning (days) to 30. This is the lowest number possible, so a System Status Alarm (or SNMP alarm if you've configured that) will be generated when the certificate is set to expire. IP Office Manager will also generate an alarm when logging in. I haven't found a way to eliminate this that doesn't do away with all the application security altogether. If you come up with something please let me know in the comments. I will update my post and give credit where it is due.    


IP Office Server Edition/App Server/UCM Can't escalate to root

Avaya, in their infinite wisdom, decided to take away root access over SSH connections. This was put into place for versions 10.1 SP7, 10.1 SP8, 11.0.4.2, 11.0.4.3 and 11.1. Of course, this makes it very difficult to provide remote support!

Naturally Avaya's customer base revolted at this, so Avaya will be bringing back root access for upcoming releases. Well, that doesn't help if you're stuck now! To that end I've figured out what was blocking it and created a simple workaround. It will require direct access to the system. If you're using VMWare this can be through the VMWare console, otherwise you will need physical access to the server. If you're working on a UC Module remember that the HDMI port will not be active until you reboot. You should be able to execute the commands without a monitor, but being able to see what you're doing is a lot easier. Follow these steps to allow SSH access to root. You will still need to log in as Administrator when connecting via SSH, but you will no longer get the dreaded 'incorrect password' error.


  1. Log in to the server (direct-connect) as root, using the Security password
  2. enter the command usermod -a -G wheel Administrator 
That's all it takes! Now you should be able to SSH to the system and log in as Administrator. Once logged in enter the command admin, then log in again. Now you can enter root and log in with the security password.

IP Office Manager Upgrade Fix

IP Office Manager 11.0 FP 4 SP 1 has a bunch of 0-byte files. When Manager tries to transfer these files to the IP Office the IP Office’s internal file server rejects the files because they are invalid. This should be fixed in future releases, but until it is there is one published workaround from Avaya: recreate the SD Card. This is a pain and requires physical access to the system, so I have come up with a better way to fix the problem.


The error I see most often is 400 - Bad Request

I have created a zip file containing a number of replacement files. You can download the file from my Google Drive here.

Once you have downloaded the fix you can extract the contents of the IPO11Fix.zip file:


Copy the folder system (right click and copy, or left click and then CTRL+C):
Navigate to the IP Office installation directory and find the common memory card folder (in a default installation that would be C:\Program Files (x86)\Avaya\IP Office\Manager\MemoryCards\Common\). Paste the system folder that you had copied into this folder and overwrite all the files when prompted:


You may be prompted for Administrative access. Provide the access if requested:
