You're essentially sharing a large PBX with that provider's other customers, but because these companies use multi-tenant segmentation, your PBX will appear dedicated to you. This engine will take care of routing calls on your VoIP network and out to others as well.
Remember to watch out for ambient noise on your end of the call as well. Train signals, traffic, or even outside conversations can be very distracting to your callers and project an unprofessional image. Don’t forget the beep. Every millisecond – yes, millisecond – between the end of your greeting and the beep is time callers could potentially drop the call. That’s why the anticipated beep should sound the moment your greeting is finished. Leaving lengthy, silent gaps may cause your customers to wonder if they’ve been disconnected. Don’t give them the opportunity to hang up waiting to hear that affirmative tone. Check and then recheck your greeting. After you complete your outgoing voicemail message, play it back to verify you’ve said everything you intended to say. Then take it a step further and dial in to experience the greeting for yourself, and be mindful to contemplate the greeting from the customer’s perspective.
