Using an SPA9000 (HW ver.1.0 SW ver. 6.1.5) with two FXS connected residential phones. The 9000 is attached to an Aztech DSL600EU ADSL modem and sends to an INEXQ ISW054t 4 port router that runs residential network IP traffic through the 9000 with QOS enabled.
The problem is the configuration works perfectly for 24-48 hours and then the following happens where:
1)1 1) The two ITSP FXS/DID’s return busy signals to the outside callers and the ITSP failover number (tried enabled/disabled) transfers fail. But users can still can complete outgoing calls with the same FXS/DID’s.
2) An outgoing ITSP FXS/DID call only returns the first two outgoing rings to the local initiator but the call continues until the recipient/voicemail picks up, confusing the local initiator who believes the call has failed.
Currently warm reset (****,732668#) or cold re-boot is required to re-connect the ITSP DID’s full i/o functionality for the next 24-48 hrs.
Still new at this but we want to stabilize this system beyond this testing phase so we can export existing telco/cell #’s to ITSP DID’s and add SPA phones, but need this to operate error free first.
I have used the wizard, but read the forums here and elsewhere for configuration data to get the 9000 to work and in doing so may have inadvertently modified a variable that could be causing this issue. Or is this a result of the heavy home network IP load on the 9000?
FXS port i/o gains set to ‘4’ and it works well at that level.
Any suggestions? Or links to definitive ‘Call Progress Tones’ for my region to aide in stabilizing?
