I'm quite familiar with voipms since I have a reseller account with them for my sms service . They aren't very privacy friendly, so if you are trying to maintain anonymity there are probably better options. I successfully ported a MySudo number to my voipms.
I'll point out that MySudo seems to only use Twilio which is a developer oriented voip/sms company. You can directly make account them them and use a web interface but they aren't very private either and require a non voip number to be confirmed on the account.
If you really want MySudo (note they are proprietary) you could try running it in android-x86 which includes standard google apps I believe. Haven't tried this
