Ports and Packet Sizes
TCP and UDP Ports
The following TCP and UDP ports are relevant for the TANDBERG MPS.
* Listening sockets
Outgoing H.323 call:
First call uses 5555 for outgoing Q.931 and 5556 for H.245, next uses 5557 for Q.931 and 5558
for H.245, etc.
Incoming H.323 call:
First call uses 5555 for H.245, second 5556 etc. until it reaches 6555. It will then start on 5555
again, unless the TANDBERG MPS has been restarted in the meantime.
Layer 4 Ports Used in H.323 Meetings
Ports for TMS
Ports TMS (TANDBERG Management Suite) uses for communicating with the TANDBERG MPS
If HTTPS (port 443) is not available on the endpoint, HTTP (port 80) will be used instead

IP Packet Sizes
Audio: The TANDBERG MPS is sending maximum 320 bytes of audio per packet.
Video: The TANDBERG MPS is sending maximum 1400 bytes of video per packet.
In addition, the system needs to add the following header information (40 bytes in total) for
each of the audio and video packets above:
20 bytes IP-header•
8 bytes UDP-header•
12 bytes RTP-header•
Packet loss: Packet loss is displayed in the conference overview of the TANDBERG MPS, see MCU
Conference Overview. The number shown is the average of audio- and video- packets that are lost
during the last 2 seconds.
