I'm wondering if there's any parameter's that I can change on the SPA400 regarding PSTN connectivity. I have one customer who is experiencing that the calls are beeing dropped from time to time. This is a installation in Norway if that should matter in any way.
Would like to know first if you have any logs from the SPA400...difficult to debug.
The only thing that comes to my mind that could affect dropped call is if PSTN has activated call waiting functionality. You can check this with the PSTN provider. If so, please ask them to disable.
I haven´t got any debugs from the SPA400, it´s not that common that the calls are beeing dropped. We have another installation where the SPA9000 runs with a SIP trunk towards the ITSP and they don´t have this problem, so my first guess was a setup or confugration option I´ve missed on the SPA400.
One of our customers it's experiencing the same problem as Heivind,
he has an SPA900 with SPA400 (2 analog lines-no VOIP) and every day one or two calls drop after some minutes of conversation.
It's possible to set up the syslog to log only necessary debug data and leave it runnig an entire day ?
The only known case, call drop happens is when call waiting happens over the FXO line. Call waiting is not supported on the SPA400 for PSTN calls, so you need to disable it with your PSTN service provider (best is first to check whether you have this service enabled or not).
There´s no call waiting configured on these lines. Any way to shape the debug as Roberto mentioned above??
This link explains how to get Syslog on SPA400. Deactivate Voicemail traces.
I'm taking the case over from Eivind, and attached a debug file from the SPA400. When we tested a call from my cell phone to the SPA400, the call didn't disconnect towards the PSTN (my mobile) when we ended the call from the SPA phone, not sure if this is related to the calls beeing disconnected.
Alberto is on business travel this week.
Thanks for letting us know that a SIP trunk is going to be used.
