<div>I just changed a 2821 voice gateway from MGCP to H.323 with CUCM 6.1. After the conversion, all inbound and outbound calls work fine. The only noticeable difference is that the inbound caller does not hear ringback on the first ring. So if the IP Phone user answers the call on the first ring, the inbound PSTN caller just hears the user answer and doesn't hear ringback. Not the end of the world, but I'm wondering if there is a dial-peer or voice-port setting to adjust this behavior? </div>

<div>2821 is running 12.4(15)T7 with PRI connection to PSTN. Standard pots and voip dialpeers:</div>

<div>Any ideas?</div>
