[INTERLINKED-23] Phone number verification not correctly decoding DTMF
I created an InterLinked account and am now trying to verify my phone number. I receive the call, note down the 6 digits, wait for the announcement to finish, and start sending the 6 digits back via DTMF, but get interrupted by "try again" after entering the 3rd digit. I've tried a few times varying the time between announcement ending and starting to send DTMF, length of DTMF tone, time between tones, but it didn't make any difference. I am using a cell phone since I don't have a POTS line on the PSTN :^( so I was wondering if there might be some VoIP out of band DTMF shenanigans going on, but I got the same results blue boxing the DTMF tones too.
I suspect the problem may exist between instrument and chair given everyone on PhreakNet must've successfully verified their number at some point, but I'm struggling to think of any other ways I could be messing this up.

It does seem like there is possibly some kind of out of band DTMF issue going on, since per checking the logs, it doesn't look like any DTMF was received. We've manually verified your account so you can proceed.
