“Hi, this is George at Company Name. I am travelling today but will be checking voicemail regularly. I will be able to return calls between 5-7p.m., eastern standard time. If you need immediate assistance, please press zero to be transferred to the office manager. I can also be reached at [email protected], and will be responding throughout the day. Thanks for calling!”

Of course, we want to know as soon as an incoming voicemail is saved, so again, it’s Twilio to the rescue. By adding a few lines of code to our Python script, Stacey and I each get an SMS notification telling us there’s a new message. Note that Twilio’s API requires a separate call for each message to be sent, which is why the similar code repeats once for Stacey’s phone number and then again for mine. If you plan to send bulk messages from Twilio, I expect that you can build a list of phone numbers and loop through them with the API call. Since we only have two contact numbers and don’t expect to add any more, I decided not to loop through a list of two elements.
There is a limit on the VM length but you can modify it. This line of the script has a maxLength parameter, represented in seconds: resp.record(maxLength=”30″, action=”/handle-recording”). If you changed that value from 30 to 120, for example, the max VM recording length would be 120 seconds, for example. Note that the voice mail recording is not stored on the Pi; it’s stored on Twilio’s servers, hence the per minute charge from Twilio for the recording and the service. Is it possible to use it as CCF (conditional call forwarding)? after enabling the forwarding option it should play some pre recorded messages on the basis of who calls ?
