E.164 numbers 
E.164 is the standard that defines normal phone 
numbers. They may contain digits from 0-9, *,
and #. H.323 differentiates between these 
numbers and “H.323 addresses” that may 
contain alphanumeric characters. Several
Gatekeeper implementations do not differentiate 
between E.164 numbers and H.323 addresses. 
If you encounter problems, try specifying the
number as an H.323 address.
