Hi list, After several tries to understand the subtil description in the h323.conf to be able to make the next scenario I was presented the following error messages by asterisk. Can somebody tell me please what I am doing wrong. Scenario: Gatekeeper (h323) --> Asterisk PBX -->(h323) Gateway Endpoints are connected to Gatekeeper. Call does come in like 999931235650087 with codec g711 and need go out to gateway at address 217.199.177.152 to terminate the traffic to PSTN. in exactly the same format. (9999 is just used as a prefix) In my understanding I need to make a h323.conf that looks like this to be able to achieve this. ; The NuFone Network's ; Open H.323 driver configuration ; [general] port = 1720 bindaddr = 0.0.0.0 amaflags = default disallow=all allow=all ; turns on all installed codecs allow=g711 dtmfmode=rfc2833 gatekeeper = 200.84.48.85 AllowGKRouted = yes context=gateway [gw1] exten =>9999XXXXXXXXXXX,1,Dial(h323/${Exten:1}@217.199.177.152) [gw1] type=h323 prefix=9999 context=gateway So when I start asterisk with -vvvvvvgc the last part of the information looks like this [chan_h323.so] => (The NuFone Network's Open H.323 Channel Driver) == Parsing '/etc/asterisk/h323.conf': Found == Creating H.323 Endpoint == Setting default context to gateway WARNING[1074494336]: File chan_h323.c, Line 215 (build_alias): Keyword h323 does not make sense in type=h323 == Adding alias "gw1" to endpoint == Adding Prefix "9999" to endpoint == Registered channel type 'H323' (The NuFone Network's Open H.323 Channel Driver) == H.323 listener started == Using PARENTGK@dC8543051.dslam-03-16-4-02-01-01.urb.dsl.cantv.net as our Gatekeeper. == Parsing '/etc/asterisk/enum.conf': Found Asterisk Ready. So I checked the list and found some patch to update chan_h323_c to version 1.11 for the error message but I do have the most recent CVS update that tells me the version is already on * Version Info: $Id: chan_h323.c,v 1.12 2003/12/10 23:34:47 jeremy Exp $ This is as far as I get. Is there anybody that can give me some hint where I am going wrong? Probably some interpretation error at my site in how to configure an alias when the type=h323. I also have the h.323 debug trace but this is just presenting an immediate relase complete because it does not know how to handle the traffic due to my not so ingenious config file... Box is on RH9 with 1.12.2 and 1.5.2. openh323 and pwlib. asterisk is taken december 14th from CVS. Tjapko.
