[Asterisk-Users] SPA-3000 Disconnect tone detection in Spain, Peru and Colombia ?

[makevuy]

Hello everybody,

I'm a new user of * and I just bought a Sipura SPA-3000 to make a home voip
installation.
I actually have a problem when a PSTN user calls and hangs up. The
disconnect tone is not
detected by the SPA, the the call continues and, for example, leaves an
empty message on
the voicemail before hanging up (because * hangs up).

How could resolve this problem?. 

I set,

Detect Polarity Reversal:yes
Detect Disconnect Tone: yes, with the default value.

Thanks a lot for your help ;)
