I'm trying to debug some issues with my first SPA9000+SPA400+SPA932 installation.
All firmware updated. System initially configured with the wizard, then manually.
There are 6 SPA932 handsets.
Voicemail is configured for each user and we're using 2 PSTN lines through the SPA400.
The SPA400 is connected to Line 2 on the SPA9000.
No SIP trunks at this stage.
The voicemail & PABX functions of the system seem fine for internal calls.
The voicemail stops working when both PSTN lines are in use.
The voicemail functions recover once the PSTN calls are finished.
I've read somewhere that more than an extra SPA400 is required if you have more than 2 PSTN lines and want voicemail, but I thought the configuration in question should have been OK.
Calls made through the PSTN lines have almost continual short duration breaks for the person listening on the outside.
Listeners inside the netork do not experience any breaks.
I would be grateful for any pointers to help me debug these issues.
Thank you, Nigel
