​                                WHY USE AN ON SITE SYSTEM INSTEAD OF HOSTED

Hosted systems have many of the same features that the Yeastar has but there could be extra charges for features that the in-house system includes. If you have need to record conversations for professional or training purposes the monthly charges can be significant depending on the number of users that are recorded. Bandwidth is another consideration. Hosted systems use bandwidth not only for outside calls but use twice as much calling extension to extension as each needs to contact the cloud server. The on site system rides on the LAN and uses none for extension of voice mail calling.


The SIP Trunk provider that we use provides unlimited call paths which means that there is never a busy signal or waiting for an outside line. There are several plans starting at $105/month and include at least six telephone numbers from any area code or local exchange. Call us for detailed information and rates.​​
