• For a Mediant Software SBC on AWS using an Elastic IP, AudioCodes says to set the NAT rule Target IP Mode to Automatic so the device learns the public address itself, and to use Manual when an external NAT device is involved. in context
• For Mediant VE in HA mode on Azure, AudioCodes says to create two NAT rules using the local source IP addresses of the active and redundant devices and not to use the Source Interface parameter. in context
• For Mediant Cloud Edition behind NAT, AudioCodes says two NAT Translation rows are typically needed, one for the signaling interface and one for the Media Components' media interfaces. in context
• The AudioCodes Mediant Software SBC NAT Translation table replaces the source IP of SIP messages from an IP interface with a public address in the Via and Contact headers and the SDP o= and c= fields. in context
• AudioCodes states the NAT Translation table applies to both signaling and media interfaces of the Mediant Software SBC. in context
• For Mediant Software SBC on cloud platforms other than AWS, AudioCodes says to set Target IP Mode to Manual and configure the public IP address explicitly. in context
