SPA8800 random call drops SW 6.1.7(GW)

[danlunderville]

Dear experts, 

I am having issue where a SPA is connected to 4 FXS lines and registered to my asterisk. There are random call drops and I cant seem to find reason. I captured syslog, Can someone please help me take a look at these logs and tell me what happened.

Logs are attached.

Both calls has ended because of  "Pstn Activity Time Out".

Disconnect tone, so long silence or CPC may be (mis)detected.

Check PSTN settings. They should match PSTN line specification (it's telco operator specific, so ask operator for it).

Thanks Dan for replying. Here are my PSTN Disconnect settings.

Unfortunately, I don't know what particular values comply with your's operator requirements.

Set all Detect* to no. If it help, re-enable it one by one in attempt to identify the cause.
