Change MXIE Softphone setting

There are 2 configuration options you can try

1. Use TLS encrypted connection

This is a preferred configuration.

Important: To be able to use TLS, TLS communication port has to be enabled on the phone system and set to 5061. You can find the menu below in MXAdmin Provision -> SIP and RTP, SIP settings tab. If you change settings in this window system will have to be rebooted to apply settings.

Change MIXE Settings under File -> Preferences -> Softphone to 
1. Local SIP port 5062
2. Registrar SIP port 5061
3. Set protocol TLS
4. Click Apply

2. If you can’t bind to softphone using TLS, use alternative SIP UDP ports

On Zultys phone systems  configured by Vatacom there is an alternative UDP SIP port  6060 .

Change MIXE Settings under File -> Preferences -> Softphone to
1. Local SIP port 5062
2. Registrar SIP port 6060
3. Keep protocol UDP
4. Click Apply
