Quadro 2x drops call after approximately 10 minutes

[jab]

hi - I'm hoping someone can suggest a solution. Calls are dropping out after approximately 10 minutes. Might be 9 one time, 11 another. Not sure that it happens every time. The line just goes silent. No particular error log that I can find.

Any suggestions about where to look and what to look for?

Quadro 2x latest f/w

Thanks

Hi John,

as soon as it happens again, download the system logs from Quadro and send them to Epygi's technical support mentioning the time of the call, called and calling numbers.
