Hello,

While doing some testing, I've noticed some strange behavior in my SPA3000:

(1) I've setup two VoIP accounts on Line1 and PSTN. Both showed "registered" status on SPA3000's "Info" web page.
(2) I then called PSTN line from a Cell phone. Got the dial tone for PSTN-line VoIP provider.
(3) Dialed a number with VoIP service on PSTN line. This way, the PSTN line (gateway) was busy and I was using PSTN VoIP service.
(4) I then picked up the phone attached to the line1 of SPA3000. I heard a normal dial tone and dialed a local phone number (which goes through the PSTN gateway "gw0").
(5) Since my PSTN line was busy, I heard a re-order (busy) tone. But it drops my PSTN line VoIP call.

Also, it left my PSTN line in some strange (I guess, off-hook) state. When I tried to call a local number from Line1 phone, I heard busy signal. Then I tried calling my PSTN line from the Cell phone and I heard busy signal on my PSTN line.

Well, I then rebooted (power cycled) my SPA3000 to release the PSTN line. After power cycle, my SPA works fine.

Does any one know how can I avoid this type of problem? Or does any one encounter a similar problem? If so, how was that resolve?

Just fyi, I upgraded my SPA to the latest available firmware (3.1.7).

My guess is that the SPA3000 didn't detect your PSTN line hangup correctly. Who provides your PSTN line?

Of course, the fact it also drops your VoIP call is a bug and should be fixed.

Thanks PhoneBoy. I played with my PSTN line VSP and this time my SPA-3K was behaving differently. Previously, on both of line1 & PSTN lines, I was using Net2Phone. Now, I left my line1 VSP as Net2Phone and changed my PSTN line VSP to Teliax. I repeated the same steps as before but this time I heard a busy tone every time I tried dialing out to my PSTN gateway (gw0). The PSTN line did not drop either.

Now, I've another issue with my PSTN line VSP (Teliax). I can dial out from PSTN line VSP but when I tried calling PSTN line VSP from my Cell phone, I heard a busy tone. However, when I use Teliax on line1, it was working fine for both outgoing and incoming calling. I guess, I've missed some setting some where in my SPA.

Does any one has had some success in setting Teliax on PSTN line?
