i just setup correctly my voice gateway and the caal manager. Both device can communicate i think. Now i want to know what is the minimum configuration i have to complete in the CCM in order to make outgoing to PSTN call and receiving call from PSTN.
voice gateway cisco 2801 with VWIC-2MFT-E1
great news, for the incoming as i mentioned all you need to configure is the incoming CSS and the significant digits under the GW config
the CSS needs to reach the phones and the significant digits how many are you going to use
ie, if you receive 10 digits but you only use the last 4, set the significant digits to 4.
if you already receive 4 and have DIDs then there is really no need
if this helps, please rate
