For a comparison of Universal Voice and integrated telephony adaptors, see Adobe Connect audio and video conferencing options.
Adobe Connect Universal Voice uses a component called Adobe Media Gateway to send and receive audio from a SIP server. Install Adobe Media Gateway and configure it to communicate with a SIP server. The SIP server can be hosted by a third-party or be a part of your company’s infrastructure. SIP providers are also called VoIP providers.
Megjegyzés:
Adobe Connect supports two-way communication and video devices.
-
Install Adobe Media Gateway.
You can install Adobe Media Gateway on the same computer as Adobe Connect Server or on a dedicated computer. You can deploy Adobe Media Gateway on a single computer or in a cluster of servers. The Adobe Media Gateway installer is part of the Adobe Connect Server installer. See Install Adobe Connect using the installer.
-
Open ports. See Adobe Media Gateway ports and protocols.
If a firewall uses NAT, see Configure Adobe Media Gateway to communicate from behind a firewall that uses NAT.
-
To install Adobe Media Gateway on a cluster of computers, see Deploy Adobe Media Gateway on a cluster of servers.
-
To create a dialing sequence and test the audio connection, see Configure audio providers for universal voice.

If you can’t hear audio in an Adobe Connect meeting, see Troubleshoot Universal Voice issues.

Adobe Media Gateway listens for requests from Adobe Connect Central Application Server on the following port:
Adobe Media Gateway initiates a connection with Adobe Media Server like a regular RTMP client. Adobe Media Server listens for Adobe Media Gateway on the following port:
Adobe Media Gateway communicates with the audio conferencing provider over the SIP and RTP protocols on the following ports:
Direction |
Rule |
|---|---|
Adobe Media Gateway to Internet |
SRC-IP=<Server-IP>, SRC-PORT=5060, DST-IP=ANY, DST-PORT=5060 |
Internet to Adobe Media Gateway |
SRC-IP=ANY, SRC-PORT=5060, DST-IP=<Server-IP>, DST-PORT=5060 |
Adobe Media Gateway to Internet |
SRC-IP=<Server-IP>, SRC-PORT=5000_TO_6000, DST-IP=ANY, DST-PORT=ANY_HIGH_END |
Internet to Adobe Media Gateway |
SRC-IP=ANY, SRC-PORT=ANY_HIGH_END, DST-IP=<Server-IP>, DST-PORT=5000_TO_6000 |
Megjegyzés:
ANY_HIGH_END means any port above 1024. The default port range is 5000-6000. You can change these values in the Application Management Console. Alternatively, you can also update these values from the sip.xml file of Adobe Media Gateway, by configuring the nodes portUpperLimit and portLowerLimit.
Megjegyzés:
You may not need to complete this task if your firewall is SIP-capable or SIP-aware. Also, in some cases the ALG (application-level gateway) for SIP in a firewall can cause problems. If you can’t enable successful communication through ALG, disable ALG for SIP in the firewall and use the technique described in this section.
Network address translation (NAT) is a process that allows networks to use fewer external IP addresses and to obscure internal IP addresses. NAT changes the IP address and port number of packets flowing out of a network. The internal IP addresses are changed to an external IP address. NAT also tries to direct responses sent to the external IP address to the correct internal IP addresses.
When Adobe Media Gateway is behind a firewall that uses NAT, it may not be able to receive packets from the SIP server. NAT changes the local IP address and the UDP header (packet source) IP address to match the external IP address.
The UDP header IP address is the same as the Adobe Media Gateway external IP address. Therefore, if the SIP server uses the UDP header IP address to send a reply, the reply finds Adobe Media Gateway.
The contact header IP address is the same as the Adobe Media Gateway local IP address. Therefore, if the SIP server uses the SIP contact header IP address to send a reply, the reply can’t find Adobe Media Gateway. The local IP address is hidden behind the firewall and not visible to the SIP server.
The following image shows how NAT changes the IP addresses at the firewall:
-
SIP server (internal interface). The packet is processed when it reaches this interface. If the SIP server uses the UDP header IP address to send a reply the reply reaches Adobe Media Gateway successfully. If the SIP server uses the contact header IP address, the reply cannot reach Adobe Media Gateway.
The following image shows a successful configuration in which the SIP contact header IP address is same as the Adobe Media Gateway external IP address. This change allows packets to be routed back to Adobe Media Gateway from the SIP server.
To ensure that Adobe Media Gateway can receive packets successfully from a SIP server, do the following:
-
On Adobe Media Gateway, open the [root_install_dir]/conf/sip.xml file in a text editor. (The default root installation folder is C:\Program Files\Adobe\Adobe Media Gateway.)
-
Create a <globalAddress> tag under the <Profile> tag. Enter the Adobe Media Gateway external IP address, as in the following:
... <Profiles> <Profile> <profil e I D> s ipGateway </profileID> <userName>141583220 00 </ userName> <password></password> <displayName> sipGateway </displayName> <registrarAddress>8.15.247.100:5060</registrarAddress> <doRegister>0</doRegister> <defaulthost>8.15.247.100:5060</defaulthost> <hostPort> 0 </hostPort> <context> sipGatewayContext </context> <globalAddress>8.15.247.49</globalAddress> <supportedCodecs> <codecID> G711u </codecID> <codecID> speex </codecID> </supportedCodecs> </Profile> </Profiles> ...Megjegyzés:
If the external IP address is dynamic, you must reconfigure Adobe Media Gateway every time the external IP address changes.
-
Restart the Adobe Media Gateway service. See Start and stop Adobe Media Gateway.
-
-
On the firewall between the Adobe Media Gateway server and the SIP server directly forward the SIP port (5060 by default) and all RTP voice ports (5000 - 6000 by default) toward the Adobe Media Gateway server. The ports open at the firewall must be the same as the ports open on the Adobe Media Gateway server.
Megjegyzés:
The servers can communicate without port forwarding. However, without port forwarding calls may disconnect unexpectedly, especially after long durations.
A high log level can cause audio glitches when the load on Adobe Media Gateway is high. Higher log levels write more information to the log. Writing to the log uses processing power and leaves less power for transmitting audio. For best performance, Adobe recommends setting the log level for audio data to 4.
Adobe Media Gateway installed on a computer with two processors can make 100 calls simultaneously. To handle a higher load increase the number of processors or add more Adobe Media Gateway servers to the cluster.
To deploy a cluster of servers, install Adobe Media Gateway on its own computers and install Adobe Connect Server on its own computers. Do not install Adobe Connect Server and Adobe Media Gateway on the same computers.
When you deploy Adobe Media Gateway on a cluster of servers, Adobe Connect Server handles load balancing and failover. Adobe Connect Edge Server does not require any additional configuration.
-
Run the installer on every server in the cluster and choose to install Adobe Media Gateway. See Installing Adobe Connect.
Megjegyzés:
For information about deploying Adobe Connect Server in a cluster, see Deploy a cluster of Adobe Connect servers.
-
Select Adobe Media Gateway settings and click Add to add and configure additional Adobe Media Gateway servers.
Megjegyzés:
Use the Application Management Console on one server to enter configuration parameters for all the servers in the cluster. The Application Management Console pushes the configuration settings to every server in the cluster.
If you can’t hear audio from a Universal Voice audio conference in a meeting room, do the following:
