auto dialing to ip and an audio conference bridge

[kdechert]

is it possible to dial an internal call over ip then add an audio call that has to dial a conference code or chairperson code through the conference scheduler automatically. I can get it started but it (the TMS) will only dial the main digits and not the codes

Has to go into touch tone mode and then add the pin, probably worth raising a ticket with Tandberg to see if you can get this functionality added in.

I presume your talking about DTMF here. If so, then TMS does not support sending DTMF tones with EPs, only the MCU and MPS per the TMS Product Support Document.

In Tandbergs, DTMF is implemented differently in the EPs versus the MCUs and the driving application for TMS was connecting MCUs to external audio bridges, so that is where the implementation in TMS is.

As it's not supported by the codec then TMS support isn't going to help, i.e. have to get the seperate DTMF support into the codec first.

The MCUs support a second parameter for the dial command which the DTMF properties are entered into so the DTMF stuff can be seperate from what number to dial and know what to send after the connection is made. BTW, if you do this with an MCU, then you need to use a participant template in TMS where you enter the DTMF string.

What you are describing looks like TCS-4 dial strings which are normally used for gatewayy calling. Look that up, and if it doesn't help try calling 866 TANDBERG (866.826.3236) for help.

DMTF AKA Touch Tone (I'm in the UK).:D

So you can use DMTF through the Codian Bridge?

What is a DTMF?

DTMF (dual tone multi frequency) is the signal to the phone company that you generate when you press an ordinary telephone's touch keys. In the United States and perhaps elsewhere, it's known as "Touchtone" phone (formerly a registered trademark of AT&T). DTMF has generally replaced loop disconnect ("pulse") dialing. With DTMF, each key you press on your phone generates two tones of specific frequencies. So that a voice can't imitate the tones, one tone is generated from a high-frequency group of tones and the other from a low frequency group. Here are the signals you send when you press your Touchtone phone keys:

Digit.............Low frequency........High frequency
1.......................697....................... 1209 Hz
2.......................697....................... 1336
3.......................697....................... 1477
4.......................770....................... 1209
5.......................770....................... 1336
6.......................770....................... 1477
7.......................852....................... 1209
8.......................852....................... 1336
9.......................852....................... 1477
0.......................941....................... 1336
*.......................941....................... 1209
#.......................941....................... 1477

A number of companies make microchips that send and receive DTMF signals. The Telephony Application Program Interface (TAPI) provides a way for a program to detect DTMF digits.

thanks for all of your help guys it makes sense because we can manually dial the dtmf tones from the system TMS does not support this function, from what i have read here and after speaking with Tandberg, we will need a bridge/MCU to add this functionality. again thanks for all of your help
