This isn’t going to cause any problems is it, Brian?

I’ve seen a few posts on the list stating a few problems recently when upgrading.

I must say that we are running in a production environment.

Hello all,

Got a bit of a strange one, we appear to be getting DTMF tones on incoming calls when the caller hasn’t even pressed any keys.

It normally happens with 10 seconds or so after the call has been answered.

Here is the log of it happening earlier: -

I’m very sure the caller isn’t dialling “A” or “B”!

Running on ISDN via a TE121 card using E1 (euroisdn).  Freeswitch version is “FreeSWITCH Version 1.0.head (git-b9b7266 2012-02-10 12-23-58 -0600)”.

Currently there is a “bind_meta_app” in the config which binds a script on the B leg of the call which parks the call – I haven’t tried turning this off yet to see if it’s this.

Wondering if anyone has any ideas or has come across this before?

Thanks in advance.
