Jim, thanks for the update. Maybe this is why I've never had any problems since all of my installs are with the same CLEC on a #5.

In NASCAR there is a term (cautions breed cautions) Now caller ID only shows number. Does 5ESS not show name and number? I have never had so many issues with PRI's or T-1'S until this dx-120 came into my life.

The 5ESS definitely delivers name and number, long before some other CO switches had this capability. It's not the 5E, it's the DX120. PRI signaling parameters in the United States all follow the same set of standards as mandated by the FCC, regardless of the brand of CO switch that provides the service. Many of the newer switches, better known as "soft switches" don't seem to follow this same standard for some reason.

You may want to check with the CLEC and make sure that they aren't emulating 5ESS custom instead of NI2. That's been known to give us a few headaches, but from what I've seen, that's about it.

The new circuit may be programmed to deliver number only. Check with the provider.

The telco says they are sending number and name, so why would it work on the previous settings (DMS100 I think) prior to 5ESS and the DX-120 does not have any settings that could be adjusted unlike the Inter-tel Axxess? The telco said they are sending the entire stream but only the number shows. The DX has setting for start and stop digits but that would not apply to this or would it?
