I am currently trying to setup a SPA9000/400 system to connect to a single PSTN line.
I have used both the latest configuration tool (2.1) and the beta version (220.127.116.11).
Both devices are running the latest firmware versions.
I have done a factory reset on both devices twice and come up with the same result.
The actual setup is:-
1 x standard analog phone plugged into the Phone 1 port on the SPA9000
1 x WIP310 wireless phone
connected to "2Wire" wireless adsl modem/switch
SPA9000 connected through internet port (not ethernet)
SPA400 connected to PTSN line through line 1
We are not using external VOIP
When I check in the SPA9000 under Voice > Info , Line 1 is registered.
I have checked the phone line works by connecting the phone directly to it and I can make and receive external calls.
The LED for line 1 on the SPA400 flickers very quickly constantly. It turns off when the line is physically disconnected from the device. I have checked the documentation and it is only has the LED and off, on or flashing (not flickering quickly).
I can make calls backwards and forwards between both extensions without a problem.
I have checked the number (9 in this case) is used for an external line.
The configuration is localised for New Zealand and looking at previous posts (https://supportforums.cisco.com/message/3094153#3094153) I have changed the localisation setting to what this recommends with no change
I am obviously missing something really simple. I have read through the various discussions and checked what has been suggested.
