             Project: Asterisk
          Issue Type: Information Request
      Security Level: None

When I give the ooh323 show peer HQ in CLI I get:
Name:          HQ
FastStart/H.245 Tunneling:no,no
Format Prefs:  (alaw:60)

AMA flags:     Unknown
IP:Port:       192.168.202.252:1720
OutgoingLimit: 0
rtptimeout:    60

BUT when I do a call in  /var/log/asterisk/h323_log I get:

What is the method that is used for DTMF?    rfc2833 or as finally mentioning in log H.245(signal)?
