Wrong forum. 2801 is not a kind of Small Business class device.Your chances to get valuable reply are rather low.

Please [ DELETE ] your question here and recreate it in more suitable forum. Consider IP Telephony.

Although I'm not expert on the matter, you should describe your environment - especially type and configuration of outgoing line the particular test call is routed to. And debug output of such interface (like debug isdn q931 if it is isdn line). The Q.850 code 34 may be true response from uplink line. In such case there may be nothing wrong with your's configuration, you may be blocked by upstream telco provider for some reason.
