H323 to Aastra PBX requires DTMF

[V01p]

Hi,

I am using OOH323 (Asterisk 1.8.21) to link to an Aastra BP250.
Calling from the Asterisk to the Aastra works fine.
When I call from the Aastra to the Asterisk, there is no speech. Once I press a DTMF button on the Aastra PBx, then a long tone is heard on the Asterisk phone (SIP) and the speech channel opens. Why is this?

I have attached my ooh323.conf:

[general]
port=1720
bindaddr=192.168.100.95
h323id=asterisk
e164=100
callerid=asterisk
gateway=no
gatekeeper=DISABLE
tcpStart=10000
tcpEnd=20000
udpStart=10000
udpEnd=20000
faststart=yes
h245tunneling=yes
h245inSetup=no
t38support=disabled
userInputMode=TONE
amaFlags=default
accountCode=H323
directmedia=no
logfile=/var/log/asterisk/h323_log
mediawaitforconnect=no
context=from-trunk
allow=ulaw
dtmfmode=h245signal
progress_setup=8
progress_alert=8
signaltracelevel=6

[BP50]
type=friend
host=192.168.100.15
port=1720
dtmfmode=h245signal
faststart=yes
h245tunneling=yes

Many thanks

Hope it helps...IPU doesn't support fast start...

Hi,

Thanks for the reply. With this fault I have tried both with it enabled and disabled but the fault remains the same. However, I have permanently adjusted my ooh323.conf below:

general]
port=1720
bindaddr=192.168.100.95
h323id=asterisk
e164=100
callerid=asterisk
gateway=no
gatekeeper=DISABLE
tcpStart=8100
tcpEnd=8100
udpStart=8100
udpEnd=8100
faststart=no
h245tunneling=no
h245inSetup=no
t38support=disabled
userInputMode=TONE
amaFlags=default
accountCode=H323
directmedia=no
logfile=/var/log/asterisk/h323_log
context=h323
disallow=all
allow=alaw
dtmfmode=rfc2833
progress_setup=8
progress_alert=8
