Incoming Numbers (DIDs)
Each Coms
Hosted VoIP account is issued with a UK Direct Inward Dial (DID) phone number that can handle 100 simultaneous calls. Typically, the DID number is directed to your Auto Attendant, which manages the call and transfers the caller to their chosen department or extension number. We can also issue international DID numbers.

Call Queuing 
In conjunction with Coms’s group hunting feature, the Call Queueing feature enables callers to be queued before their call is routed to an agent. When callers enter the queue they are informed about the number of callers ahead of them and, optionally, the estimated waiting time. Customers can define as many queues as they need and have the ability to forward callers to physical
IP phones, or virtual accounts which have been configured for group hunting. Each queue can have its own "music on hold"..

Call Restrictions / Station Restrictions
Prevents certain types of calls from being made or received by particular stations. For example, phones in public areas can be blocked from making calls to external numbers, so as to prevent unauthorized users from incurring toll charges. Phones in certain areas may be blocked from receiving external calls in order to limit employees’ ability to take personal calls. A wide variety of restrictions are available, covering incoming calls, outgoing calls, toll restrictions, code restrictions, and differential treatment for internal and external calls.

Multiple Call Appearances
Multiple Call Appearances allow each station to have two or more appearances of the user's primary phone number. Each appearance gives the user the ability to handle one call. Consequently, Multiple Call Appearances allow the user to make and/or terminate multiple calls simultaneously. Unlike an analogue multiline phone, the station needs only one line (and one phone number) for Multiple Call Appearances. When the user is involved in a call on one call appearance and another call is offered on a different call appearance, the user may use the Caller ID information to decide whether to answer the ringing call appearance or let the call be forwarded to voicemail. To answer the ringing call appearance (or make a second simultaneous call), the user simply puts the first call appearance on hold. Calls on different appearances can be combined together to form a three-way conference call, supported by ComsX via the follow-me feature. The primary phone number (account) is provisioned on the
IP phone, and all the other appearances are created as accounts with the follow-me, configured to the primary account.
