1A First Alternative

VoIP: summary

This manual is intended for 1A telephony users. This manual explains how to log in on the Phonetool and a phone. You need to be logged in on both to be able to make a call with the phonetool.

1A-telephony consists of the 1A VoIP module (the telephone exchange) and a number of SIP phones (phones suitable for VoIP). Every user can manage his/her personal settings with the Phonetool.

The general settings for 1A-telephony are controlled by your own 1A administrator (see the manual Telephony for the 1A-manager). You can manage your personal settings yourself through the Phonetool. For more information about daily use of 1A telephony, see the manual VoIP: daily use.


To complete this manual, you will need:

  • Telephony on your 1A-server. No telephony yet? Please contact your 1A-partner.
  • A computer with the Phonetool installed (this is done automatically on Windows computers in the company network)
  • A SIP phone connected to the 1A-server
  • Your username and password
  • Your user number for telephony (if unknown, ask your 1A administrator)
