SIP Trunk Cloud Features

Call Forwarding

A Call Forwarding allows an incoming call to be redirected to a mobile telephone or other telephone number where the desired called party is able to answer. You can set any number, even international numbers.


This feature will allow you to send and receive messages with your DID Number (US and Canada DID Numbers Only). Please note that this feature is for regular customer usage. No automation, telemarketing, bulk sending or receiving will be allowed.

Virtual Fax

The Virtual Fax feature is used for sending and receiving a Fax (facsimile) with the Aspen Connnect service using a DID number specifically dedicated to Faxing.

Automated Attendant

The Automated Attendant can be used to present a recording to the people calling to your DID number and also give them the chance to enter the extension of the person or department they want to reach. For example, caller will hear "Thank you for calling XYZ Inc, for Sales press 1, for Service press 2", etc.

Call Queue

Callers can be placed into a Queue when all SIP Trunks are in use. While in Queue, callers will hear music and periodic announcements

Call Hunting

The Call Hunting feature allows you to have incoming calls ring on different destinations designated as "Call Hunting Members" one after another, for a specific amount of time, until one of those Members takes the call.


When a DID is routed to a callback entry and a call is placed to it, the number will return a busy signal. The system will then callback the specified number and present the user with a dial tone.


Direct Inward System Access ( DISA ) allows you to use our system for placing outgoing calls, even if you are not close to your office. In this case you just would need to dial to your DID number and to provide a 4 digit PIN number, then you can dial out to any number.

Time Based Routing

Time Conditions is a feature that allows you to route your incoming calls to different destinations depending on the time of the call. For example, you can have a Time condition for your Non-Business hours and all the incoming calls you receive will be routed to a recording or the voicemail directly.

Caller ID Filtering

This feature allows you to filter the incoming calls to your DID numbers to route differently than the current DID routing that come from specific numbers, area code or even anonymous numbers. For example, if you receive annoying incoming calls from a telemarketing company, you can create a filter to route all the calls to a recording that plays the message "That number is no longer in service, please hang-up and try again".


Cloud base When an emergency (e911) call is placed over the Aspen Connect network In the USA, the physical address you will enter at the time of e911 registration for a specific DID will be passed along to your local PSAP, providing the dispatcher at the PSAP with the exact location where help is required.d voicemail for your SIP trunk telephone numbers (DIDs).

Ring Groups

The Ring Group feature allows you to have incoming calls to be redirected to different destinations that are included in your Ring Group, where a member of the group is able to answer. When you receive a call to a DID routed to a Ring Group, all members of that group will ring at the same time until one of them answers the call.

Call Detail Records

The Call Detail Records (CDR) allows you to obtain detailed information of your incoming and outgoing calls.
