Hi,<br><br>Any advice on this one ?<br><br>Sometimes off-hooking a Snom 320 handset doesn't answer a multi-extension call : phones keep ringing while handset remains silent.<br>This occurs for 1 to 5% of incoming calls.<br>
<br>The setup is bristuffed 1.2.10 Asterisk with Junghanns QuadBRI and 6.2.x firmware Snom 320.<br>Every call comes from ISDN network.<br><br>Thanks in advance<br>
