Trunk and PBX Features

Our VoIP system can simple 'trunk' calls to/from your own PBX - it is perfectly normal for you to have your own office PBX, such as a FireBrick or an Asterisk server for example and for your equipment to provide you will all the 'PBX' type functionally that you require. However, you can also have SIP phones register directly against our servers and use the PBX functionality that we provide. Or, indeed, have a mix of the 2 - e.g. we can route calls to you by SIP (trunk), but we can also record calls.

Incoming Features Tab Overview:

These are the features on the Control Page, under the 'Incoming' Tab.

Recording

AAISP can record all call, just incoming or just outgoing, as either wav, mp3 or ogg.
Recordings are in stereo - with the 2 parties on separate channels.
Callers can be warned, with a pre-recorded announcement, that the call will be recorded

Queuing

Calls to this number will get ringing even if the target is busy
When the target is available, the call will be put through
Applies to SIP phones only

ACR

Anonymous Call Reject - callers who withheld their number will be rejected

Voicemail

Calls after a certain time can be sent to voicemail
Record your greeting by calling 1571 from the SIP phone registered to the number

Timezone

Callers will get a pre-recorded message saying that the person they are calling is in a different time zone, and will say what the time is there.
Set to Local to disable this feature

Syslog

You can set a syslog host to get syslog messages for all incoming calls to the number
Works for group rings and so on, even if you are busy or DND, etc.
It advises your number, the caller number, and caller name if known
Also see status page post

Profile

The time range that a number is in service
a number can have multiple time

Multiple Targets

Incoming call routing is configured on the Control Pages. Call Routing is based on setting the 'Target' - a number can have multiple targets, e.g., can be routed to a SIP phone as well as a mobile, and multiple other numbers. Indeed, you can also register multiple SIP phones against the same number, and calls will go to all the SIP phones that are registered.

Delays

Each target can be given a delay (0–30 seconds). E.g., you can have your number ring your SIP phone immediately, and then also ring your mobile after 10 seconds.

Number Announce

Put a number in to here, and a message will be given to callers that the number has changed and the number entered will be read out as the new number. The call will then end.

Fail

Number to call if the call fails to get though to the configured endpoints (i.e. a registered phone). i.e., if the registered phones are unavailable, then call this mobile number.

This can be used alongside voicemail, in this case, the call will go to voicemail and have the message played but rather than having the option to record a message the call will be transferred to the fail number. Ie:

Incoming call --> (optionally ring phones) --> Play Message --> Divert to Fail number

This is useful where you want to play a message before ringing someone else - e.g. 'Thank you for calling, we're redirecting you to our on call engineer now.

Transferring Calls

Transferring calls is supported, and with VoIP this is usually handled by your telephone. i.e., your phone would have a Hold or Transfer button, which enables you to either Blind transfer or perform an assisted transfer.

Targets in Detail

A phone number can be given many targets, each target has a delay, so you can control which phones ring first etc.

SIP Phone

You can register multiple sip phones to our server. (single phones if you're on the legacy A server).

Tag

The Tag is 4 characters that will be prefixed to the number and shown on your SIP phone display (if it has one)

The tag is set to 'aTag'

The above screenshots are from a Snom 715 and a Snom 821 showing incoming calls with a tag of "aTag".

The SIP for a tag is shown in the From field:

From: "aTag07508xxxxxx" <sip:07508xxxxxx@voiceless.aa.net.uk>;tag=2015012110443100001

Your Server

We can route calls to your own SIP server, fill in the details of your server here. We will try IPv6 and IPv4 if they are available.

We will look up SRV records if there are any and will follow those. SRV records make routing SIP to you very flexible. SRV records are able to specify the SIP port used, in this case we will try that port. SRV records also allow you to specify multiple hosts with priorities. SRV records will help you create a resilient SIP system at your side by using multiple SIP servers etc.

Also Ring

These are up to 10 other numbers that we'll send the call to. They can be other numbers you have with us, or can be any other number. e.g. mobiles, international etc. - any number which you can normally dial from your account. The charge for the call will be the same as if you were dialling the call normally from your account.

Call Gate - IVR

Simple Call Gates are supported, where by a number can be called and a message played back such as 'Please press 1 for Sales, 2 for support...'. The system will then put the call to a corresponding number.

To set this up:

Set the 'Main' number can to always to go voicemail, or to go to voicemail after an amount of time.
Fill in some of the Also-rings to go to the DDI of the various targets you want
Enter a 'fail' number, as this will be used as the default number to call if no digits are keyed by the caller
Register a phone to the 'Main' number, dial 1571 and record your 'Please press 1 for Sales, 2 for support...' message

This then works as follows, once the caller has called in and has been answered with the voicemail message, the user can key a digit. If there is an also ring number set up for the corresponding digit then the call is put through to that number as a divert.

If there is a fail number set up as well as some also ring numbers then the fail number is used as a default if no digits are keyed. If there is a fail and no also ring then the fail number is used immediately after the announcement. - this then works as a greeting before a call is put through to phones.

Outgoing Tab Features Overview

Record

Same as Incoming feature

Centrex

This allows you to use the last 1, 2 or 3 digits of your phone number to call other numbers in your block. e.g. if you have 2 numbers 01344400001 and 01344400002, then you can call each other by using 001 and 002 if you set Centrex to 3. This is also used when you transfer calls between your numbers.

Presentation

This is the outgoing Presentation Digits that are set when a call is made from this phone number. e.g., we can set something other than their phone number here. There is a charge and a process for this and we'll need paperwork to prove the number is yours. Contact Sales for more details.

Local Prefix

This is an area code, (e.g. 01344, 020) that will get prefixed to local numbers. Useful for people with an 03 number wanting to dial local calls without the area code

IP Lockdown

Registration and calls will only be allowed from this IP address or range (in CIDR format).

Access

Define the level of outgoing calls allowed. This is defined by setting the maximum call price per minute, set separately for National and International calls.

Bill Warning

We will send you an email when your monthly bill reaches this amount. This does not block the account, it's just an advisory message. We will send the email to the email set on the Number and also the email the Login.

General VoIP Features

Hold Music

We don't have any hold music, however, what we have is a quiet comforting "beep beep" every 3 seconds.

We do pass on the "on hold" signal through to our carriers and may well get passed on through to the PSTN, ISDN and even mobile systems. This means the far end may well be told that they are on hold, and their side may display "on hold" on the screen of the phone, and the other side may well play their own hold music. This is not always the case, some types of interconnect lose the signal, but in many cases this gets all the way to the far end phone system.

VOIP Security

VoIP accounts can be compromised, so care is needed to this does not happen. Please see our VoIP Security page for more information. VoIP Security
