Talk:Multi-frequency signaling

#1DSS/NPTSN/Mountain Pacific Telephone Company
If the #1DSS 'CO switch' is in fact a CO switch on the PSTN, I'd like to know what it's CLLI code is for verification purposes. As stated before, I have strong reason to believe that the '#1DSS' is no more than an asterisk PBX running special code and dialplan that allow it to (badly) emulate MF trunks. I think most people would hardly consider this to be a 'CO switch' and any such switch would surely have it's own registered CLLI. Furthermore, a switch built on asterisk would not have real trunks using MF, it would have some emulation of the behavior. It is even likely that the 'trunk' is a SIP based IP trunk using out of band signalling for the initial dialed number. 128.174.11.96 (talk) 22:45, 3 August 2019 (UTC)

In a message left on my user's 'talk' page, the editor at 68.204.13.180 admits that the mountain pacific telephone company and #1DSS in question belongs to him or has some strong relation to him in some way. This seems to point toward the self promotion motive I mentioned before.

It has been made clear that the NPSTN, Mountain Pacific Telephone Company, and its "#1DSS" switch are personal hobby projects operated by a few friends, and not a legacy telephone company or a part of the PSTN. Because of this, I have removed the claim that they have a telephone exchange using MF signaling on the PSTN. DrDeke (talk) 00:26, 6 August 2019 (UTC)
