I am a new user of the OBi200 (but experienced with the PAP2T). I really like the OBi device, but I wish it had a way to easily let the caller direct a speed dial call to a specific trunk. Sometimes I'd prefer not to use the default route. This is not a problem if I am entering the entire number -- I just use the **X prefix. But I have found no way to let this work if I am using a speed dial, either a speed dial in the OBi itself, or one in my phone.
So, how about this solution: Allow the **X by itself, i.e., a **X followed by a hangup, to be interpreted as a request to direct the next outbound call from that Phone Port to the specified trunk (SP1, SP2, etc.). There is already a precedent for this: It is is the way one-time CODEC selection (*4711, *4729) works now. If the **X code cannot be used because it is itself defined by the OutboundCallRoute Dial Plan, then give us another Star Code that will do the deed. I suspect a lot of folks would thank you for this option.
