Mediant 500 E-SBC
Parameter Description
between the user agents. In some scenarios, the call is
established despite the media not being synchronized. This may
occur, for example, in call transfer (SIP REFER) where the
media between the transfer target and transferee are not
synchronized. The deviceperforms media synchronization by
sending a re-INVITE immediately after the call is established in
order for the user agents to negotiate the media (SDP
offer/answer).

[0] Disable = (Default) Media synchronization is performed
only if the RTP mode (e.g., a=sendrecv, a=sendrecv,
a=sendonly, a=recvonly, and a=inactive) between the user
agents are different and synchronization is required.

[1] Enable = Media synchronization is performed if the
media, including RTP mode or any other media such as
coders, is different and has not been negotiated between the
user agents.

[2] Never = Media synchronization is never performed.
