low bit rate codecs (such as g729a). Otherwise, the SPA
will not relinquish these resources until the end of the call
even if the called party did not indicate support for these
codecs
Notes:
1. A codec resource is considered as allocated if it has been included in the SDP codec list of an active
call, even though it eventually may not be the one chosen for the connection. So, if the G.729a codec is
enabled and included in the codec list, that resource is tied up until the end of the call whether or not the
call actually uses G.729a. If the G729a resource is already allocated and since only one G.729a resource
is allowed per SPA, no other low-bit-rate codec may be allocated for subsequent calls; the only choices
are G711a and G711u. On the other hand, two G.723.1/G.726 resources are available per SPA.
Therefore it is important to disable the use of G.729a in order to guarantee the support of 2 simultaneous
G.723/G.726 codec.

[2-9]xxxxxx
US "local" number
1xxx[2-9]xxxxxx
US 1 + 10-digit long distance number
xxxxxxxxxxxx.
Everything else (Int’l long distance, FWD, ...)
Note
: If IP dialing is enabled, one can dial [user-id@]a.b.c.d[:port], where ‘@’, ‘.’, and ‘:’ are dialed by
entering “*”, user-id must be numeric (like a phone number) and a, b, c, d must be between 0 and 255,
and port must be larger than 255. If port is not given, 5060 is used. Port and User-Id are optional. If the
user-id portion matches a pattern in the dial plan, then it is interpreted as a regular phone number
