[asterisk-users] Problem with Asterisk and SPA-3000
Hello everybody, I have a very strange issue with a Linksys SPA-3000 (1 fxo + 1 fxs) used as PSTN gateway to asterisk in a small office. Everything works just fine, except that sometimes, and it seems that only for long incoming calls, the IVR menu appears on the middle of the call(like a three way call, call goes on with prompts playing over the parties). Dialing an extension at the prompt at that time actually works but disconnects the original extension (and transfers the PSTN leg to the new extension as normally). At the CLI there is nothing but a new incoming call from the SPA, exactly as the original call. It seems to happen with both asterisk 1.2 and 1.4, I am quite lost, Does anyone know what could be causing this problem? -- Iván Stepaniuk Alba Fotónica S.L. www.albafotonica.com ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

The SPA-3000 is notorious for falsely detecting DTMF tones in regular voice, and when it thinks it hears DTMF, it will produce a short real DTMF tone that's only audible to the SIP side of the device, not the PSTN side, or out of band SIP DTMF message (dependent on how you have the device setup). I'm guessing you have your IVR setup so that a single keypress triggers it, and the SPA-3000 thinks it hears that key. I would suggest to not have any single key start your IVR, as the SPA-3000 only ever seems to incorrectly detect and generate one DTMF tone at a time (it never generates a sequence, just one random key's worth of DTMF).

Thanks Andrew. This is true, we do have false DTMF detections/playback
(Lowering RX gain really helps on this). However this does not seem to
be related. The only way to get to the IVR is through the 's' extension
on the context in which the SPA is registered. The SPA has a built-in
dialplan that is set to something like (S0:s). Asterisk context
shows is the following:
[sip_pstn_linksys]
exten = s,1,NoOp(Caller-ID-number: ${CALLERID(number)})
exten = s,n,NoOp(Caller-ID-name: ${CALLERID(number)})
exten = s,n,Set(CALLERID(name)=Externa SPA PSTN)
exten = s,n,GotoIf($[${CALLERID(num)} = pstn1]?private,1)
exten = s,n,Goto(menu,s,1)
exten = private,1,Set(CALLERID(number)=Privado)
exten = private,n,Goto(menu,s,1)
