One can try to enable Packet2Packet bridging, but this will only work if certain conditions are met: 1. Both sides have to be SIP 2. Both sides have to have same audio codecs and same payload size (for instance 20ms) 3. Both sides have to have video support disabled 4. Both sides must not have options for DTMF processing (such as tT, instant ...

Local Bridge (Asterisk 11) / Packet2Packet Bridge (older Asterisk versions) Media is proxied by Asterisk, but relatively efficiently. The RTP comes in to the RTP stack and goes directly out without manipulation. Here is an example of what RTP debug looks like:

What is Locally Bridging? : Asterisk

The old "native" bridge is called a remote native bridge. The old "Packet2Packet" bridge is called a local native bridge.
