[VoIP] Cnet tandem stacking

[Lee Spenadel]

Jayson,

I've noticed the problem that you mention about not being able to break
dialtone on my SxS.  I'm not sure yet why that is happening.  Each tone to
pulse converter is functioning properly on the switch, so it would appear
that something in the zap channel is not passing DTMF at that point.  

I have dialed into and out of my switches until all circuits have been tied
up (testing my all circuits busy intercept) and this is where I get the
problem.  I curious if anyone has an idea on why this is happening.

Lee

Hi,
I just did an experiment where I dialed into Lee's SXS, then out to his
Asterisk DISA, then back to my own voicemail where I left a message. When I
got the message, I could hear myself hanging up, then probably Lee's SXS
hanging up too. Neat! I did try going to SXS, then to DISA, then back to
SXS, since he does have two talk paths not reserved for coin phones, but
although I did get a second SXS dialtone, my DTMF digits weren't getting
through, so I couldn't get back over to Asterisk again! Talk about a tandem
stack! Now if only other people had analog switches with trunks to Asterisk
systems, we could really create some long calls, with some actual analog
routing!
