Is there any commercial telecommunication related product which was
developed by Erlang(e.g. switch,SCP,IP,SDP...)?
How about the performance of Erlang?

Indeed there are several. These include Ericsson's ATM switch
(about 700 000 lines of source code) and a special purpose PABX
(5000 000 lines of code). But don't get the idea that Erlang is
useful only for telecom products, Erlang has been used for a wide
variety of applications. On avaerage the total time required to
build products is about a quarter or the time used when a more
conventional approach is used. this is both because of Erlang and
because of the incremental design approach it allows

Good enough for our extremely time critical telecoms
applications!

Yes many.
You can read about some of them in

Jolly fast for our kind of applications. No so good for pure
"number cruching".
