trunk groups) must be administered.
The maximum for the connected media
server (S8300, S8500, or S8700-series)

they both use the same TLS link, since
they use the same IP addresses for the
C-LAN circuit pack and EMMC Server.

1. The actual number of SIP trunks for the EMMC feature may vary due to other SIP applications such as SES for
SIP endpoints and OPTIM (Off-PBX Telephony Integration with Communication Manager) wireless endpoints,
as well as the platform configurations. The total number of SIP trunks that Communication Manager can
support is 2000.
