I have this exact same issue with the SPA3000, I'm assuming it must be a SPA3000 bug?

Hi,

        These days I run into something quite odd.
        I have an [EMAIL PROTECTED] that was modified to meet our requirements.
We have a completely funtional DISA which we use pretty much all the time. I works flawlessly with incomming SIP calls from several providers, IAX calls from FWD and with ZAP.

Recently we came out with a situation where it doesn't work... with a SPA3000 PSTN Line. You can call, navigate de IVR, log in into our app, and then when you go to DISA, and DISA plays the dialtone... whatever you dial is not recognized...

This was REALLY odd... so I made a network capture with Ethereal, and... the SPA actually STOPS sending the RTP Events after the second dialtone...

To verify this, I created an IVR which played the dialtone, and verified that it was true.... no RTP DTMF events (RFC2833) are sent after the SPA listens the second dialtone.

I just reviewed the 87 pages PDF of the SPA3000... and didn't find anything about such "feature". Now I am going to try to figure out if it has something to do with the tones recognition of the SPA. I the meanwhile I had to write a little DISA-like app, based on something I found on this forum, without the dialtone.

        Did anyone find out anything about this issue before?

REGARDS!!!
