[Asterisk-Users] oh323 sending tech-prefix??

[Anthony Law]

Hi

I have tired using the below syntax but could't go through, I wonder if my
syntax is wrong. Please kindly comment.
Btw I am using asterisk-0.7.1 with oh323-0.5.7

exten => _1613XXXXXXX,1,Dial,OH323/8750${EXTEN}@192.168.3.66

Error Below

to determine sequence number from ''



Regards,



Anthony
