Gateway Registration Type: H323-GW or VOIP-GW

May 11, 2010 in Blog with 2 Comments

The determining factor for whether a gateway registers with a TYPE of VOIP-GW or H323-GW relies entirely on the “allow-connections” commands entered under “voice service voip.” Essentially, if your gateway is functioning as an IP-to-IP gateway, it will display H323-GW.

The commands that make or break this:

voice service voip
allow-connections h t h
allow-connections h t s
allow-connections s t h
allow-connections s t s

After adding or removing these, make sure to bounce your gateway registration with the gatekeeper using “no gateway” and “gateway.”

I just verified this. Here is a snapshot without the commands listed above:

HQ-RTR#show gatekeeper endpoints
GATEKEEPER ENDPOINT REGISTRATION
================================
CallSignalAddr Port RASSignalAddr Port Zone Name Type Flags
————— —– ————— —– ——— —- —–

After adding the commands listed above:

HQ-RTR#show gatekeeper endpoints

    Good write up, as always but I guess you meant to say “Essentially, if your gateway is functioning as an IP-to-IP gateway, it will display H323-GW.”
