Hi Cisco and community..
Need help with PSTN disconnect issue on SPA-3102-GW ATA.
[I have the latest FW release, 5.2.13 for this unit.]
Setup:
ATA is configured as PSTN-VoiP gateway. Line1 is registerred to remote PBX, PSTN is registerred to same PBX but different number.
PSTN calls are setup to divert to PBX extension after 20 sec's.
Scenario:
Incomming PSTN call, Line1 phone rings (ok so far), 20 secs expires call diverts to PBX extension and call is placed - everything ok.
Either caller or callee hangs up and call is terminated.
Issue:
Incomming PSTN call, Line1 phone rings - now sometimes caller hang-up just before the 20 secs divert time.
When this occurs, the phone on Line1 rings a litle longer, then diverts to PBX extension. Issue now is, PBX extension answers but caller has hung-up and PSTN line remains off hook for ever until PSTN line is physically removed from socket OR unit is power cycled.
My observations
PSTN to SPA calls: (Answered through Line1)
If Line1 disconnects call - I see:
{Last PSTN Disconnect Reason: VoIP Call Ended}
PSTN to SPA calls: (Answered through Line1)
If PSTN disconnects call - I see:
{Last PSTN Disconnect Reason: PSTN Disconnect Tone}
PSTN to SPA calls: (Diverted to PBX extn)
If Line1 disconnects call - I see:
{Last PSTN Disconnect Reason: VoIP Call Ended}
PSTN to SPA calls: (Diverted to PBX extn)
If PSTN disconnects call - I see:
{Last PSTN Disconnect Reason: PSTN Disconnect Tone}
The issue here is, if a caller hangs-up just before the PSTN answer delay time, the unit will continue to ring for a few sec's then divert to the extn nominated in the dial-plan.
Now, the SPA-3102 cannot detect PSTN disconnect as this call is now a VoiP call, so the PSTN side will remain off-hook until the far end hangs up.
Is this a bug, or by design ?
Any suggestions??
