if I'm on SRST mode the ATA won't register with the GW, is there a few lines that I'm missing or what should I do in order to get the ATA to register with CCM

I have a 2851 GW running Version 12.4(3h)

I have this problem too.

To start with the easy you have your ATA's in the same device pool as your phones. If not make sure the device pool they are in have the proper SRST reference.

Are they in the same VLAN as your phones, and are you using "strict-match" in the "ip source" statement for call-manager-fallback?

I'm not using the strict-match

this is what i have

ip source-address port 2000

Is it in the voice VLAN? If you are using "Default Gateway" for SRST, you need to make sure that the default gateway is the gateway with SRST on it...

yes, the ATAs are in the voice vlan

I'm not using a default gateway


secondary-dialtone 9

max-conferences 8 gain -6
