[asterisk-users] Best Current Release for Long Term Use

[Danny Nicholas]

I beg to differ with you Jared.  Since I don't have your email, I'll post
this here.  Create this call file.
Channel: DAHDI/g1/5551212
CallerID: SIP/104
MaxRetries: 1
WaitTime: 60
retryTime: 5
Application: playback
Data: /var/lib/asterisk/sounds/you-sound-cute

On my "test" machine using a TDM400P, the playback would occur in a manner
such that the user would only get 50-70 percent of the message.  

Changing 5551212 to a cell phone number would create another 5 to 10 percent
loss of message.

Changing DAHDI/g1/5551212 to a local SIP extension would deliver the message
in its entirety.

On my "live" machine (TDM410P), the DAHDI call actually waits for a
connection, then plays the message after a 1/2 second pause, so I STAND
CORRECTED, AT LEAST SORT OF.  The bug is reproducible on the TDM400P but not
TDM410P.  

Here is dahdi_cfg from test box

If this is an analog line connected to an FXO port, then Asterisk has no
way of telling whether or not the remote party has answered the call or
not.  This is entirely due to the way analog signaling works, and works
exactly the same under both Zaptel and DAHDI.
