Suppose we dial HDFC Bank then till the call gets through to the Main Telephone no SS7 is used . Howver after that we hear Prompts like ” For English Dial -1, for Hindi dial 2″ , “For Credit Card Dial 1 , For Loans Dial 3” etc . Now in all these prompts what is the porotocol we are using – definitely not SS7 . Please clear this doubt

In this case No Protocals…only DTMF Tones.
They are in SPEECH Band-DTMF Tones.
After Call establishment…you dont use any protocal for this.

AKKU,
Dont mix up with ISDN Network where you can use signaling while call is in progress.
GSM is not a pure ISDN Type.
It uses ISDN Flavours.

I feel that even in the IVR there is some SS7 signaling part used . Please confirm
S.Vijay Guest
Dear Ashok ,
Yes I agree…
C7 is used for CALL Setup in IVR.
But Akku is talking abt after call setup.
I hope you can understand.

Hi Sejal,
I am not working in IVR Related Systems.But I have handled in past.
It is just like any other small switch with some minimum telecom system functions.
Above than any advanced EPABX.
If you can see that practically than discuss it. you will understand clearly.
