Thank you Tim for quick answer... BTW, I posted here first, and only cross-posted on DSLR because the post here went into moderation queue... I also appreciated a call back from Support manager suggesting simultaneous ring option. In short - I am impressed by VOIPo service (and, to reiterate, I am quite impressed by VOIPo's telephony quality). It is the secondary features that I am griping about!

Simultaneous call won't work because there is no information of the "real" called number.
So, I don't know how VoicePulse arranged integration with YouMail from business perspective - but since the users are getting free version of YM service - it should be beneficial to VP and any other VSP as well... Just a thought
