IP Address

You can use the IP address of the first active media (port greater than 0) for message manipulation. The IP address is taken from the media "c=" field (the "c=" field below the "m=" field) of the SDP body. Note that if the "m=" field doesn't contain a "c=" field, the IP address is taken from the global "c=" field (the "c=" field at the top of the SDP).

Syntax:

sdp.address
