View Full Version : Tandberg Gateway - DTMF Tones Dropped

Hello VTCTalk (newbie here, first thread, appreciate your patience),

My issue occurs when Audio Callers telephone dial into the Tandberg Gateway IVR number, with intention of entering a Personal Conference on the MPS-800. The Audio Caller is prompted to "Please dial your party's extension followed by the # sign," and quickly enters the E.164 Alias for the Personal Conference followed by #. Under most circumstances, the Gateway does not "hear" all the DTMF tones and hands off an incomplete E.164 string to the MPS-800, which in turn, receiving a request for a non-existant Personal Conference extension, immediately drops the caller. For example, if you dial 1001# too quickly (10 is our MPS-800 prefix, 01 for the Personal Conference), the Gateway often misses the double-digit 0, "hearing" 101#. I have opened up a ticket with Tandberg and escalated it to Engineering - wondering if anyone has experienced this.

I'm attaching a diagram of my ISDN Gateway infrastructure.

Also, you would think the MPS-800 would be a little kinder, and offer a message to the caller to the effect of "You have entered an invalid conference ID" and offer the caller another chance to enter their conference extension - professional outsourced audio bridges like Incom offer this courtesy.

Hi

I´m also having trouble with the DTMF tones like you describe it. The times I tried, the Tandberg did not registered the eight digit pin code. The Tandberg required eleven entry’s before is responded that it all eight was entered. This makes it impossible to join a conference that don’t have a pin code with the same number because I don’t know if is the first or the last digits that the Tandberg don’t manage to registered

I´m also having trouble. I´m doing a call from T1700 MXP (F6.3), registered to Cisco GK and using a Rad Via IP 400 ISDN Gateway, calling to Tandberg Gateway G3.2 abroad and could not get connect with a Tandberg Endpoint F5.4. With Polycom PVX doing the samething on the same LAN of T1700 MXP I can place the call and no problem. Tried with F5.4 and F6.3 and got the same results, the Tandberg Gateway can not "hear" the DTMF tones in order to proced the call. Any idea would be very welcome....
