Streams that can sometimes be captured
If the Branch Gateway is the WAN router of the following streams, they can be captured:
• H.323 Signaling from IP phones on the LAN to an ECC over the WAN
• DHCP when the DHCP server is behind the WAN (using the Branch Gateway DHCP relay
capability)
• RTP stream on an IP phone on the LAN to a remote IP phone
