There are several. If you do not have a good butt set, may I suggest T3 Innovation TLA300-1 Tel Scope Telco Telephone Line Analyzer. Not only will it give you the digits dialed, it also provides Caller ID. This set is also very helpful if you are in a terminal and have a mix of digital and analog lines to test.
From Mike Sandman: Tone-Master TM-16 PLUS with RS-232 Serial Port
From Ebay: Fluke ts52 pro. It will do both digit grab and Caller ID. They go for around $70 and I know you LOVE Fluke test equipment.

I have a top of the line Harris butt set and I would like to get the Fluke but I just can't justify it since my current one is in such good shape.
I looked at the TM-16 PLUS and it looked like it did do what I wanted but after reading it again I think it does and even more. The only problem is the price.
The T looks very good but I already have a good but sett.
Thanks for the info.
