Hi all! Please I need someone that have already done an H.323 - SIP gateway to help me with some problems. I can stablish calls from a SIP telephone to a H.323, but I can't do vice versa...

Hi! I am in a H.323 network with a gatekeeper and some terminals. Asterisk is a gateway between this network and the SIP network. Now I can do calls from de foreign network (SIP) to the locla (H.323) but I don't know how to do the inverse. The H.323 terminals use NetMeeting, and when I try to make a call, it says that the number dialed must be registered in the gatekeeper. How can I register

Hi all! I am using ohphone (well, I am trying to) to make calls. I will make an H.323 - SIP Gateway but I don't understand the architecture of all this. What is the exact role of asterisk? It can be used as gateway, that I know, but what else can he do? Is it necessary to have ohphone to make calls or asterisk can also do that? So when the gateway it is going to be implemented how is it

I am lost!!!!!!!!!! Please help me! See you. Mireia

Dunno why your phone isn't allowing you do negotiate g711u but I can tell you how to upgrade the firmware.

It'll go out to the net and check the firmware revision and change it if required. I've done

Hi! I am trying to do a SIP/H.323 gateway. I want that the SIP proxy server (I suppose that this is asterisk isn't it?) has all the information about the user's registration. So, when a request arrives at the gatekeeper from the H.323 network, this one tries to make multicast to all the others gatekeeper and also the Gatekeeper Asterisk. Asterisk then looks for if the user called is a

we are trying to use asterisk for converting SIP to H.323 calls. asterisk (0.9.1) runs on the same linux (Redhat 8) box of our gatekeeper (gnugk version 2.0.8). the calls are going out through a cisco gateway. when I make a call from a SIP phone to a PSTN number reachable through the cisco gateway: asterisk diaplays Aug 5 23:24:26 WARNING[1255648560]: chan_oh323.c:2898

I have two devices that I want to talk to each other: 1. an Asterisk PBX 2. a Damm Cellular TETRAFLEX digital radio system (www.damm.dk) both devices are effectively "gateways" because they have many subscribers behind them. The Damm Cellular system controller is based on Windows-XP Embedded and its sub-systems used the OpenH323

I'm having trouble registering my asterisk to a cisco gatekeeper. I do not have control over the gatekeeper, and I know that it has user info defined in an LDAP. I have a user name and a password that I can use, but I can't seem to get Asterisk to register on the gatekeeper. I can't find exactly how I'm supposed to define the gatekeeper in the h323.conf file. This is the response

Hi, I want to configure * to use a gatekeeper for routing calls to H.323 endpoints. I imagine it will work like that: * (chan_h323) will query the gatekeeper where to terminate the dialed number and the gatekeeper will return the information for the h.323 gateway. after that chan_h323 will try to make the call to the gateway it has received from the gatekeeper. so instead of duplicating a

Hello all, It's me again. I would like play with calls between a H.323 client and a SIP client through * inside my LAN. For that, on host 192.168.1.20, I use GnomeMeeting (GM20) and Asterisk; on host 192.168.1.25, I use SJphone (SJ25) as SIP client on Windows and I register into * with a username, no password. The 3 files oh323.conf, sip.conf, extensions.conf are in attachment. In the same

Hello, I'm trying to setup an asterisk extension to be attached to an H.323 gatekeeper so that an asterisk application (Astcc) answers H.323 calls from any terminal logged into the gatekeeper.
