To do a VoIP capture with a TMG7800, it is required to:

- Use Wireshark on the laptop.
Once the physical setup is ready. It is possible to start capturing the RTP.
Preparing Tmedia for Capture
- Access the telecom unit (TMG7800-TE, TMG7800-DS3 or TMG7800-STM1) you want to capture using telnet.
telnet [eth0 IP address of the telecom unit]
For example
telnet 172.16.123.45
The prompt will now be:
