A question we are often asked by our customers is “what is the number for…” , whether that is for shortcuts  for Gradwell services and departments or general numbers such as the speaking clock or directory enquiries. To help you out, we have compiled a handy list of the most useful numbers below:

100 – Gradwell Customer Service

123- Speaking clock

141 – Prefix on dialled number withholds PSTN Caller ID

1471 – Gives last number that called

150 – Gradwell Sales

152 – Gradwell Billing

153 – Gradwell Porting

154 – Gradwell Partner Support

160 – Echo test: listen to what you say echoed back (for example to test latency)

185 – Voicemail: record voicemail prompt, or pick up voicemail for a  group (e.g. sales) or for any individual extension

186 – Voicemail: Used for specific extensions to pass  calls directly to the mailbox. Format 186nnnnnnn – (n=7 digit extension number)

187 – Voicemail: Used for specific password protected extensions to pass calls directly into the mailbox and login. Format 187nnnnnnnpppp (n=7 digit extension number p=4 digit pin code)

188 – Record voice prompts (the message played on answer) and menu prompts (IVR)

 Another useful free service,  as advertised on Money Saving Expert, is 0800 buster. This allows you to get free directory enquiries to your mobile, using your contracted minutes (if you get them). This also means if you have VoIP on a mobile app you can use this service and call these numbers for free!

To make it work you dial a special number (which you can get here), you can then enter your 0800, 0808 or 0500 number and miss out on the charges associated with these numbers. More information on how to set up this free service can be found on the Money Saving Expert link.

    The dial a special number above should read 0800, 0808 and 0500 numbers, not 0845 numbers.
