Do you have overlap dialing enabled on the outgoing interface? There used 
to be a bug where the Asterisk zap channel tried to send the overlap 
digits before the SETUP ACK was received. 

There was a patch applied to cvs, but I am not sure it worked correctly 
always. I have not had time to remove our very _very_ ugly workaround to 
see if cvs works or not.

I am seeing this too, only I'm using 100% PRI.  I'm not sure how it would be a 
Zap problem since the Zap driver doesn't see any digits when you're dealing 
with PRI.

Several tries later and it suddenly works  It's very sporadic.

Re: [Asterisk-Users] Zap channel occasionally misses dialing the first digit

[Asterisk]

have a look at http://www.voip-info.org/wiki-Asterisk+zap+channels
Here it tells you that you can specify a wait period.
Here are some examples of complete Dial commands as they might appear in 
your Dialplan 
:

  exten => s,1,Dial(Zap/1); Ring extension on channel 1
  exten => s,1,Dial(Zap/1r2)  ; Ring extension on channel 1 with distinctive ring #2 

  exten => s,1,Dial(Zap/1,30) ; Ring extension on channel 1 with 30 second timeout 

  exten => s,1,Dial(Zap/2/5551234); Dial 5551234 on channel 2
  exten => s,1,Dial(Zap/2c/5551234)   ; Dial 5551234 on channel 2 with answer confirmation 

  exten => s,1,Dial(Zap/2/ww5551234)  ; Wait 1 second then dial 5551234 on channel 2 

  exten => s,1,Dial(Zap/g1/5551234)   ; Dial 5551234 on the first available channel in group 1 

  exten => s,1,Dial(Zap/1-2/1234) ; Dial 1234 on span 1, port 2
  exten => s,1,Dial(Zap/1-2/c1234); Dial 1234 on span 1, port 2, with PRI clear channel option

I'm thinking that it may be starting the dial too early after coming
off-hook because I can just redial and have it work (or not) randomly.
Does anyone know what this might be and/or an easy way to have the ZAP
channel come off-hook, delay for 1/2 second or so, and then dial?

[Asterisk-Users] Zap channel occasionally misses dialing the first digit

I THINK.  When dialing 1+10 digits, I occasionally get a telco
message "You must first dial a 1".  When I look at the console, the
number is being sent to the ZAP channel properly.  We're talking about a
couple of POTS lines on a TDM400P.
