Tandberg MCU

[Airwave1]

Hi,

I look after a Tandberg MCU and would like to implement Password protection on all of the incoming calls to it.
My problem is that although we have many Tandberg units we also have many Sony units and with these I can not se a way to input the number password in. The reason for this is when you press one of the number keys it does not work because they are Camera presets!

Does anyone know a way around this?

Thanks

Gareth

Hi,

did you tried to press
* or # as a prefix before your passcode ?

Note that 2 methods may happen (not shure what fits here)
1. password-awareness is an optional feature introduced with H.320
It runs in the call setup /capability exchange protocol
2. DTMF awareness is an audio feature
decoding the decompressed audio for the beeps
It is usual proprietary.

Hope this helped

Airwave,

I will be getting my Tandberg MCU back tommorrow, so I hope to have some time to take a look and help. I am not familiar with the Sony units, so I am assuming that you cannot pass DTMF tones. Let me know if this is not true. If you can't pass DTMF, you can usually get by with TCS4. I need to take a look at our MCU (haven't had alot of time on it) to see how this would be set up.

Ok Airwave......I just got off the phone with Tandberg. The only way to use the password protection is if your codec can pass DTMF tones or if your system supports H.243. If anyone has a good explanation of H.243, please post it. I am still looking.

Now the guys at Tandberg asked how I would like to see password protection for legacy systems, for they are very interested in adding support (those guys are great). I explained that my experience has been with the Radvision, where you are able to use a delimiter for password protection. This delimiter is usually ** . So when dialing into the MCU, you would dial the conference number (either 323 or 320), followed by the delimiter, then followed by the password.

As an example, say I have a conference number of 555-1212 with a password of 1234. From my legacy system I would dial: 5551212**1234. This would then bypass the IVR response and send the user directly into the conference.

Knowing the people at Tandberg, if the users ask for it, they will make it happen.

Here is the link to the MCU manual. You can find the password information on page 23.

Let me know how it goes.

Thanks everyone! :D

It was a case of pressing the * button as this enables the DTMF tones.

Quite easy really!

Cheers
