I tried it from a ReadySIM account, which exclusively uses T-Mobile towers, and I got an error recording, so this may be only for contract customers. Have you any luck decoding the outpulse?

Works for me on tmo postpaid. DTMF comes in strings of 2, then 10, and then the same 2 digits, though I don't have a decoder handy.

I tried dialing seven digits but kept getting the greeting using a prepaid sim, i guess it only works on their pre-paid and post-paid service and sims, but not their mvno's like readysim.
also *182 connects you to 1800collect.
