[asterisk-users] Zapatel early media issue

[Dimitar Dimitrov]

Hi,
I have some troubles with early media with Zapatel TDM400P adapter. I 
made a simple callback function wich works by followin way:

The user call into our Asterisk box and get into the "s" extension. Then 
leaves a message and hangs. The asterisk make a call to my CellPhone and 
then plays the recoreded message.
This is a configuraction of inbound extension:

[incoming]
...
exten => s,n,Goto(ivr2,s,1)

[ivr2]
exten => s,1,Playback(vm-intro)
exten => s,n,Set(MSGFILE=msg-${EPOCH})
exten => s,n,Record(${MSGFILE}.wav|2|15)
exten => s,n,Wait(1)
exten => s,n,Playback(${MSGFILE})
exten => s,n,System(/var/lib/asterisk/system/callme.sh ${MSGFILE})
exten => s,n,Hangup()

exten => 5051,1,Wait(2)
exten => 5051,n,Playback(${MSG})
exten => 5051,n,Hangup()

The scipt which makes the outgoing call is:
###################
#!/bin/bash
echo "Channel: Zap/3/<my cell phone number>
MaxRetries: 3
RetryTime: 60
WaitTime: 30
Context: ivr2
Extension: 5051
Priority: 1
Set: MSG=$1
Archive: Yes" > /var/spool/asterisk/outgoing/callme-$1
###################

The problem is when the asterisk box call me the zap device gives the 
ring indication, after that the PSTN gives me the ring and the 5051,1 
extensions starts and plays the message before I pickup the phone.
The zap device is configured as:

context = incoming
signalling = fxs_ks
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
echotraining=800
immediate = no
busydetect = yes
busycount = 4
faxdetect = both
channel => 3

I am using Asterisk 1.4.21.2.

Thanks in advance.

Dimitar
