Telephony at Alchemy Translations

Voice over Internet Protocol (VoIP) via Session Initiation Protocol (SIP)

We usually use the app Linphone or Zoiper to make phone calls.
You may install this programme on your laptop or better mobile phone.

You need the following data:
server: 107.173.160.152
port: 5961
user name: same as your phone number
password: your password

You may also make internal calls to the staff (it's free) using extensions only, e.g.

Our main company number for the clients is +43 720 77 5362.

Zoiper for Android

The full guide is here and a small guide for Russian language here.

In short, to setup Zoiper on the first page type:

xxx@107.173.160.152:5961 where xxx is your phone extension, see examples above. In the password field type password. The rest you can just skip, it should start working already.

After you setup your phone check the following:
