Table 16: Dialing Issues
Problem or Error Probable Cause Corrective Action
The conference leader receives an
error message when trying to add a
participant’s outside phone number
(not extension) using the Web
interface.
The conference leader attempted to
add an outside phone number and
did not use the correct dialing
format.
The conference leader must type
the complete phone number that
includes country code and area
code, if applicable, with an outside
number when adding a participant
to the conference using the Web
interface.
An operator error message is
audible in the conference: “It is not
necessary to dial a 1 when dialing
this number.” The audio may be
different, depending on the service
provider.
Dial Access String (DAS) rules
have not been set up correctly.
Add additional DAS rules to allow
for the +1 to be stripped out from the
local number.
For example, 602 and 480 are two
of the area codes for Phoenix,
Arizona.
For these area codes, add the
following DAS Rules:
The result: any phone number
starting with 1602 or 1480 will have
the leading “1” stripped off,
replacing it with a “9,” the number,
@, and then the IP address.
For example, assuming that the
phone number to be dialed is
1-602-555-1212 and the IP address
configured in TCP/IP Settings is
192.168.22.55:
16025551212 becomes
96025551212@192.168.22.55
For more information, see
“Configuring Dial Access String
(DAS) Rules” on page 47.
Calls dialed from MCA fail. DAS rules contain errors. Check DAS rules for typing errors
(missing dots, slashed, etc.). For
more information, see “Configuring
Dial Access String (DAS) Rules” on
page 47.
An attempt to create a three-way
call with two users and a
conference fails. The two users are
briefly connected to one another,
but then that call drops as well.
Other users on the conference hear
garbled voice while the failure is
occuring.
SIP default settings are incorrect. Use the default SIP settings. For
more information, see “Configure
SIP Device Capabilities” on
page 24.
