Hi, is there any way to be able to dial a VC unit that is behind an extension number(ISDN), im trying to reach it from an MGC 100?
Any way that we can access it? number format?

thx

Sounds like the video unit is an IP/H.323 device sitting behind an ISDN/IP gateway like the Cisco 3526, RadVision ViaIP, RadVision L2W or Tandberg. If the MGC-100 has an audio+ card providing the capability of DTMF tone generation, then the format in your site name of your conference having attended/IVR turned on, is site_name [EXT:xxxx] where xxxx is the extension. The gateway's ISDN side answers the ISDN call and bonds any channels together, then the MGC after the call is answered, sends the DTMF tones to the Gateway's IVR which interprets them and connects to the appropriate H.323 endpoint registered with that extension alias. There is a problem of compatibility between older versions of the Cisco 3526 and RadVision ViaIP but the newest works with the MGC-100. The RadVision L2W doesn't work with the MGC for extension dialing but will work if the endpoint has a DID assigned to it in the Gateway. Tandberg gateway is compatible but you may have to tweak the conference settings (video protocol) on the MGC.

Sorry, I meant on a H.320 call, where you would dial the ISDN number eg.+44-207-950-**** and then an ext number ****.


By the way do you work at MCI Mr Valander....?
Its me ....Nuno from the UK Office....lol

Generally, a video call over ISDN, receiving an IVR to enter an extension means the endpoints are on a private LAN accessible to the public ISDN network through a gateway. If this is not your scenario, please describe more clearly what you are dealing with.

And yes, I'm a video engineer in the Chicago center of MCI Conferencing, supporting our global platform for video conferencing services, H.320 and H.323.

A new product successfully implemented in several institutions is called RMS, aimed for organizations having a need for user-friendly scheduling and conference management. The key benefits include the capabilities of managing MCU's of various brandnames, incl. Polycom, Radvision, and Cisco, with intuitive interface. This should help your client's scheduling and dialing procedures.If you need more detailed information about it, please write to offline at georgecheng@dgt.com.tw.

to return to the original question - in its traditional form, there is no way of adding that elusive extension number that I know of. And yes, its a real pain as you have to get the customer to dial in...

If I understand you correctly, you want to dial from an MGC 100 to an endpoint that has an extension. I have been doing something similiar, dialing audio participants at an extension from the MGC 100, but it can just as easily be done for a video endpoint.

First make sure there is an IVR service that does not have any IVR's set. This IVR service needs to be in the conference.

Make the endpoint name the extension, for example:

Dialthisnumber[Ext:pppp1234#]

So, to dial phone # 212-555-5555 with an extension of 1234 and press pound when complete, then extension 2345 #.

each p is to delay one second.

Participant name is:

Default-Participant[Ext:pppp1234#pppppp#ppp2345#]

The MGC manager can dial a 'direct dial' remote site via number and extension without the need for IVR or DTMF implenmentation.
An example of requirement this would be that x2 seperate organisations have endpoints behind MGC's, the implemented connections and call routes are number and extension dialling.

If a remote ISDN based site wants to dial the endpoint behind a MGC the endpoint itself will dial the number then extension via the delimted value.
However, if you want to dial from one MGC manager to another site which is behind another MGC with number and extension dialling format the way to do this is:
Within the dialling MGC manager participant details, enter the participant name as: (EXT:1234) if the extension is 1234, using the bracket, EXT and colon format shown.
Enter the participant phone number and other details as normal.
MGC 1 will then dial the destination number and request the remote MGC 2 to direct the call to the extension number within the participant name field in one go. Thus you can direct dial a number and extension from one MGC manager to a remote MGC which has number and extension implementation.
