In the Second number delimiter field, type the character used
as a second number delimiter for dialing more than one ISDN
number in setting up a 2B call. You can use the pound sign (#),
asterisk (*) or comma (,) as a delimiter in outgoing calls only.

5 In the TCS4 extension delimiter field, type the character used
as an extension number for TCS4 outgoing IP-to-ISDN call

Note Since the comma cannot be used in the Party number field of the
Multipoint Conference Control interface, we recommend that you do not use
the comma as a second number delimiter or as a TCS4 extension delimiter.
