Happy new year all together!
With the end of the year 2017 the self signed certificates of many IP Office PBXs expired. Compare my last post from July 2017. Hopefully you were able to renew the certificates of all your systems in the meantime.
If not you will get a warning if you try to login the next time.
You will get this warning, if you connect to an IP Office that uses an expired certificate.
In this case it is now the time to react. To get access to the IP Office security settings you have to adjust the IP Office Manager preferences. You have to allow secure access without any certificate checks:
This images shows how to disable certificate checks in IP Office Manager preferences
Now you are able to login into security settings and to issue a new certificate.
Hope that helps…

Recently after upgrading IP Office to release 10.1 we got calls from different customers who told us that they have about two seconds of silence at the beginning of a call. After researching with one of our customers we figured out that only 9608G phones are affected while other models (9611G, 9641GS) has no problems. In our tests showed that only outbound calls are affected and only calls with direct media (no VCM calls and no RTP relay calls) are affected.
The phone were running different firmware versions and we did an upgrade to 6.6401 as it is the latest firmware that ships with IP Office 10.1. But that didn’t help. Due to the fact that 9611 phones that run the same firmware have no issues we thought of a bad series of hardware. Continue reading
This is an update to my previous post describing the steps to create backups ESTOS applications. The older post handled backing up the earlier release 3.5 of MetaDirectory.
In the meantime MetaDirectory 4.0 has been released and with the new release ESTOS changed the installation path and the name of the service so that the current backup script will not work anymore.
So it’s time for a small update.
In order to not adjust the script every time I want to deploy it again on another server, I want a script that works for the older and the actual version. So I have to check and adjust the values for service name and paths used within the script. Continue reading
IP Office is very strong in building a network of multiple systems that feels like a single PBX for the end user. Users can call each other between sites as if they are local. You can build hunt groups with members from different sites and users can have remote users on their phone’s buttons and many more. Technically you just have to build a SCN (Small Community Network) connection between the systems and you are done. The systems exchange all relevant data of the remote systems (like users, hunt groups) and know the best way to reach a remote user.
Most times each site has it’s own PSTN connection but internal calls are handled through the SCN connection. But what happens if the connection between sites is lost? That can happen easily if the VPN fails.
Even if it is not officially documented, Avaya built in a fallback mechanism that can help you to manage such situations. There you can define what should be dialed by IPO over PSTN to reach a user if the SCN trunk is down. Continue reading
Those days a customer asked me to create a limited access to IPO for human ressources department to check for used and free extensions. Every time new staff is hired HR decides what extension the new user will get.
The challenge was to find a way to create a security user with that restricted and read read only access. Continue reading
Did you ever had the case that you get spam calls from a specific CLI? Or do you want to define a special target for calls from a single country or company?
Even if it is good documented and pretty easy many techs and many more costumers don’t know that this is possible. And to be honest I worked a long time with IP Office before I got the hint how to accomplish that. Continue reading
Sadfully Estos ProCall and Estos MetaDirectory have neither an inbuilt backup functionality nor a scheduler to backup automatically.
After searching the web for a solution I found a German article about moving the service from one machine to another: Move Estos from one server to another
It describes the steps how you can create a backup of both applications and what you have to do to restore them on another machine. Continue reading
With the new IP Office release 10.1 Avaya added a new feature called ‘Multiple Appearance Directory Number’ or short ‘MADN’ to address some customer requests. While there had been the need to be reachable under more than one single number you had to find workarounds to manage that.
You had the opportunity to place one (ore more) cheap digital or IP phone in the data center and create bridged appearance keys for that phone. It was also possible to create a hunt group for the additional numbers. The hunt group solution had some disadvantages. Enabling call forwarding or DND (do not disturb) disabled the user’s membership within the group and the user wasn’t reachable anymore. The only way a user could be reached anyway was to dial a short code using the function ‘Dial extension by number’. That works as long as the user doesn’t use hot desking because the function does not call the logged in user but the phone itself.
So we want to be able to call a user through an extra number even if his phone is forwarded or he is in a call. I had a use case where an alarm server had to call the user to play an important voice message in case of a technical issue or in different alarm scenarios like fire or violence. It is important that the alarm server is able to call the user even if his phone is not available for any reason. Continue reading
Starting with IP Office release 10 Avaya added the ability to connect One-X Portal to a Server Edition solution through a single connection rather than to add every single node manually. That makes administration much easier and you don’t have to worry about forgetting to add new connections within One-X Portal if your customer needs further nodes. But this enhancement made me struggling almost a full day in a none Server Edition environment.
Up to release 9.1 you had to add every single node of a Server Edition Solution as CSTA provider and as DSML provider. Especially if One-X Portal doesn’t run on primary server but is deployed as dedicated application server it is possible to come into trouble if remote nodes are not reachable from that application server. Since release 10.0 you can now have one single connection from One-X Portal to IP Office primary server. Primary server will kind of act like a proxy to link One-X Portal with all other nodes.

Last time we discussed how to handle Windows services with Microsft Powershell. This time we get a little deeper by restarting multiple services at once with an additional check if they all restart successful.
Let’s take a real example where one software installs three services. I often use GFI Faxmaker. It can works as a fax server behind a telephone system and is usually connected through SIP or H323. To send outbound faxes it has to receive the fax from the client as SMTP mail. Therefore the Microsoft SMTP Server service is also needed. Let’s guess we want to restart all relevant services. So we have to restart three services that come with GFI Faxmaker and the Microsft SMTP Service.
Just restarting a service is not a big deal but don’t we want to check wether all services run after the restart? Wouldn’t it be bad if we restart four services but only two of them come up again? So we will check the state of the service and if they don’t start again successfully we want to send an email to have a chance to act.
