603c77cd0da93e5e476a024643c0ef1c | 24.379 | 11.2.1.1.1 Sending/Receiving a message
| In order to participate in a private call, the MCPTT client:
1) shall send the MONP message as a UDP message to the local IP address of the MCPTT user, to UDP port 8809, with an IP time-to-live set to 255; and
2) shall treat UDP messages received on the port TBD as received 8809 messages.

603c77cd0da93e5e476a024643c0ef1c | 24.379 | 11.2.1.1.2 Session description
| For an off-network MCPTT session, only MCPTT speech is used.
One off-network MCPTT session includes one media-floor control entity.
The MCPTT client shall generate an SDP body for a private call in accordance with rules and procedures of IETF RFC 4566 [12] and IETF RFC 3264 [44].
The MCPTT client:
1) shall include ... |

603c77cd0da93e5e476a024643c0ef1c | 24.379 | 11.2.2.1 General
| The maximum number of simultaneous off-network private calls is limited by the value of "/<x>/Common/PrivateCall/MaxCallN10" leaf node present in the UE configuration as specified in 3GPP TS 24.483 [45].
