Fax calls • Your P910a does not support fax transmission.
Even if your operator subscription supports fax
transmission, fax calls will be rejected. However,
they can be diverted to another number such as
the office fax number, see ‘Divert calls’ on
page 54 for more information.
• Make sure potential fax callers do not try to send
a fax to your P910a as they can experience a
number of retries before the fax transmission is
stopped.
