When you dial into DISA, it takes a second or two to get to the “internal dialtone”.
You can’t pass the digits like that, HOWEVER, you could try putting some commas in there (depending how you’re dialing) to pause to wait for a dialtone.
In other words, if you were using a speed dial or modem to dial into the DISA, you would do 0123456,100,987654 each comma would be a half-second pause.
If you’re dialing it from a keypad, then probably not.
one another question: is it possible to add the pin-code too (if set), or is there no possibility? because of security (in this case each person can call the disa number). thank you so much.
