I suspect you are calling an endpoint at the IP address which is registered
with a gatekeeper. You cannot call this directly you must call the
gatekeeper it is registered with.

It appears that my calls are failing because of "routeCallToGatekeeper."
Does ArjReasonRouteCallToGatekeeper have anything to do with this?

Subject: [Openh323gk-users] Dial by IP fails
I just discovered that I cannot dial out through our proxy GK by IP
address. We can only dial via E.164 extension. All my video end points are
NATed behind the GK. Typically we dial via E.164 extension and our GK sends
all the signal traffic to the state gatekeeper.
What could be causing this problem?
The typical signaling path for a call made using an E.164 extension is
as follows:
our video endpoint<-->our proxy GnuGK<-->state GnuGK<-->remote video
endpoint
I've compared the log of a call to the same end point via IP address and
E.164 extension. Here are the differences that I've discovered:
IP--no ARQ is sent to state GK
IP--no "IE: Called-Party-Number" in the section labeled
"ProxyChannel.cxx(842) Q931 Received: {"
IP--no message such as "ProxyChannel.cxx(1627) Q931s GWRewrite source
for 10.2.5.127:1030: call record"
IP--proxy channel "ProxyChannel.cxx(899) Q931d Received: Facility"
Ext--proxy channel "ProxyChannel.cxx(899) Q931d Received: Alerting"
IP--has this section:
h323_uu_pdu = {
h323_message_body = facility {
protocolIdentifier = 0.0.8.2250.0.4
alternativeAddress = ipAddress {
ip = 4 octets {
<IP of state GK>
}
port = 1720
}
conferenceID = 16 octets {
02 2a cf 3c 39 f7 19 17 2a 96 63 60 19 de bf 8d
.*.<9...*.c`....
}
reason = routeCallToGatekeeper <<null>>
IP--the call is cleared with this message:
ProxyChannel.cxx(842) Q931 Received: {
q931pdu = {
protocolDiscriminator = 8
callReference = 21162
from = originator
messageType = ReleaseComplete
IE: Cause - Normal call clearing = {
80 90 ..
}
IE: User-User = {
25 c0 06 00 08 91 4a 00 04 80 01 00 11 18 11 00
%.....J.........
02 2a cf 3c 39 f7 19 17 2a 95 63 60 19 de bf 8d
.*.<9...*.c`....
01 00 01 40 10 80 01 00 [EMAIL PROTECTED]
}
}
h225pdu = {
h323_uu_pdu = {
h323_message_body = releaseComplete {
protocolIdentifier = 0.0.8.2250.0.4
reason = facilityCallDeflection <<null>>
How can I correct this problem so that I can complete calls via IP
address?
Thanks!
