You may find it useful to get the output of the SAT command 'list trace' for the call - this is likely to give a Denial cause which could indicate the reason the call was dropped.

There are a few different list trace options available. The one you use will probably depend on what information you know. Most likely you can use "list trace vdn NNN" where NNN is the number of the VDN from where you are making the call.
The document "Avaya Aura Communication Manager Denial Events" should help you to interpret any denials you get. Note that this document doesn't give a lot of information so you may also need to do some googling.

If you don't get any output from "list trace", you could check the events table:

1. Type the command "clear events" to empty the events table
2. Make the call
3. Type the command "display events" and change "category" to "all".
