Not really. I have been developer of VoIP application for about one an a half year and our clients only call us when they have a problem. Conectivity problems, delays in the audio when doing calls (due codec errors), problems with NAT, problems with the voice mails, etc... If everything is fine you just see no errors on logs and a beautiful graph expressing the increase of number of calls every month. Anything else.

Same when I was working generating telephonic bills for the clients. You will only have feedback if something went wrong.

Is that satisfaying? For my its enough; if the work have been done fine and the clients are reporting (almost) any error, I'm happy with that.

VOIP is the best! When your clients have a problem, they can't call you!
