I replaced an XTS with an SL1100 and have been having some issues with duplicating features. I have worked with NEC Tech, and seems like a lot has to be resolved via virtual extensions. I thought I would check and see if you have any better ideas.

The system trunks are ISDN.

1. Problem - Can not external transfer from Dial Action Table. Attempted what is documented in Inmail Feature guide but call would fail. Solution provided by NEC: Transfer to Virtual Extension that is set to No Answer Call Forward to external number. (All Call Forward was not working, so had to adjust timers but there is a delay).

2. Problem - If DID goes direct to station, and station is call forward external, the call will not complete....have to do the virtual extension again, but customer can not easily change external number. Going to Contact NEC in AM, but the virtual extension in this instance is not really acceptable.

3. From Dial action Table, need to ring certain phones. Once again, used virtual extensions to accomplish this, but can not get the call to go to a particular voicemail when unanswered. In the XTS, I would just use ring groups that ended up in the Voicemail with a particular VM ID. In the SL, It ends up getting the "Call can not be completed" probably because the virtual does not have a mailbox...I want it to end up in a users existing mailbox. I need to look at some notes, but think I had a similar issue with the DSX at a location in the past.

I guess I don't mind using the Virtual Extensions, it just comes down to having to sacrifice a button on the phone to perform relatively simple ring group functions. Some extensions are in multiple groups, so they can end up having 4-5 buttons that are just virtual "ring groups".

In this application, I need virtual extensions for voicemail of users that do not have physical extensions; It is municipal, so have dozens of users that will require virtual extensions, so they are a commodity that I am burning through quickly.

Just looking for perhaps some better solutions
