MiVoice Office 250/Mitel 5000 / Re: Mitel UCA App setup

« on: July 07, 2014, 05:00:28 PM »

Update this still does not work properly.

Installer updated the Mitel 5000 to latest firmware. It did not fix the problem.

They then found a setting ( I like the use of the word 'found') which enabled the internal phones to call the external UCA phones.

I then put it through a few test like ringing one UCA from another and they then failed.

Fix one problem - introduce another. Top quality this I have to say.

Installer now coming back onsite to try and work through the issues.  Which is what they should have done from day one until it actually worked 100%

Any answers on this?

This is exactly what is happening on our 130 user system setup.

We do have UCA MAS & CSM.

Currently complaining directly to Mitel UK as this has gone on for months and nobody seems to be able to fix it.

Voice is separated and on different physical switches with a Cisco routing the connectivity between phone VOIP network and main data network.

The Cisco was not setup properly for QOS to start with between 2 sites. There was a list of errors by the installers.

POE switches are brand new Netgear switches - which given the amount of traffic should have no problem at all.

I suspect the Cisco router is not configured 100% correctly.

Finding engineers that actually know the Mitel 5000 system & UCA & MAS & CSM is almost impossible.

Which is half the problem in my opinion.

Would be interesting to know if there was a fix for this thread?

Got the MBG installed and working.

Installation company sent a different installer as I refused to allow the first installer back in the building.
I simply will not tolerate installers testing their skills on our system...!

The MBG gateway is installed - we installed it as a VM.  That seemed to install quickly and fairly easily.

External phones now provisioned as Teleworker.

Although ... we can use the mobile App to call into the system but if we call to the mobile extension it fails instantly:

Call cannot be completed     from the office phone (5340e)
Then the mobile instantly notifies a missed call ...

Looking in the logs it comes up with a 404 error between the Mitel 5000 and the MBG.
Installer spent a couple of hours trying to get this working but could not.
Then decided we need to upgrade the Mitel 5000 to the latest firmware/software.
Which we will do on the 26th June.

He thinks this will cure the problem - although I have my doubts given the track record!

Would seem to me to be a setting not correct somewhere but maybe he does not know where it is...

We are still getting very bad call quality being reported by many users on maybe 1 in 5 calls.

I have to say this has not been a very good experience so far with the Mitel 5000.

One last thing with regards to the MBG - I can see on th logs some idiot in France attempting to hack into the system.
I asked the installer if we could put the IP on a blacklist on the MBG so it always ignores it.
He said he does not think there is a blacklist function on the MBG - which I find hard to believe?....

MiVoice Office 250/Mitel 5000 / Re: Mitel 5000 UCA softphone outside office without VPN

« on: May 30, 2014, 07:30:34 PM »

Using a VPN on a mobile app is something our installer "suggested" when they could not get the mobile app working.
This after they had spent 2 days scratching heads.
Using a VPN on mobile just to make it work as a soft phone for the 5000 system is a complete pain and not a practical solution.
It is what gets suggested when someone runs out of ideas - from experience.

Opening ports and forwarding opens up the system to hacking attempts and ultimately DOS attacks.  Which is exactly what happened to our 5000 system.
Ultimately bringing the system down.

We only had this installed in Feb 14. I was so unimpressed with the Mobile App functionality (i.e. being told to use a VPN) - then the firewall issues - that I contacted Mitel directly to complain.

Their answer was that the MBG should be in use. But then the installer is suggesting this has only been around for 6 months on the 5000.
I have to admit I am not sure who to believe.  I cannot understand why out of the box the 5000 in 2014 does not have a secure gateway built in for remote mobiles.

I will be getting Mitel and the approved installer on a conference call and will let them fight it out ...

MiVoice Office 250/Mitel 5000 / Mitel UCA App setup

« on: May 30, 2014, 07:07:39 PM »

I have recently had a Mitel 5000 system installed. Replacing a Toshiba system.

For me one of the main purpose of upgrading to a new system was UC functionality  - the idea of a system setup and working around a user.
This included the using mobile devices and seamlessly moving from device to another - in or out of offices.

For mobiles I have the Mitel App that only works when I am in the building the phone is installed in - which is fairly pointless.
The option - after the installer spending days trying to work something out - was to use  VPN when outside the building.

On a practical note that is completely useless. Ever tried keeping a VPN up and running on a mobile - not to mention the fact that on most handsets the VPN stops when the phone is your pocket.  More to the point why am I even using a VPN?

It seems there are plenty of installers out there who know maybe 75% of what they need to setup a Mitel system but the other 25% eludes them.

When I called Mitel UK to discuss they said it should be setup with a MBG.

On this website various people suggest using methods such as VPN (been there suffered that) or opening up a firewall and using MAC filtering to do the security.
However, surely that is a half hearted method of doing something Mitel have provided a secure app do properly? 

In our case the installer left port 5060 open and it seems half of china attempted to break into the system. Sustaining near 100% CPU usage and making the system fall over on several occasions before someone in network security realized far too late that something was wrong.  A good practical example of why using firewall rules on a corporate network is not good practice.

So the question is - what is the Mitel approved method of using the mobile app off-network/remotely on the Mitel 5000 system.
I say Mitel approved because to be honest that is what customers pay for - they don't pay for half baked ideas and work arounds...!
