Setting up HAMSIP telephony on the PC – step-by-step

This is a follow-up to “HAMSIP Telephony: Our New Toy” and describes how to set up HAMSIP completely on a Windows PC, without a SIP phone and additional network hardware.

1. Request Hamnet access

1. Go to www.hamweb.at and request Hamnet access.
2. You will receive the necessary access data (Thanks to Matthias OE5MUC!):
   • VPN server
   • Username & Password

2. Set up VPN on Windows

1. Settings → Network & Internet → VPN → Add VPN connection
2. Connection type: L2TP/IPSec
3. Pre-shared key: securevpn
4. Enter username/password

6. Test call http://44.143.70.8/

3. Request SIP user

1. Go to http://44.143.70.8/ and request a SIP account.
2. You will receive the necessary access data
   • Username & Password

4. Install and set up MicroSIP

1. Download MicroSIP from microsip.org
2. Set up account:
   • SIP server:
   • User name: (phone number without leading zeros – see example)
   • Password:
3. at 44.143.70.8/voip.php you can see all the stations that are online
4. Using DTMF Tool you can “calculate” the telephone number – the telephone number is the same as the call sign.
5. Make a test call
   • ECHO: 0032234263
   • TIME: 0081436132
