Overwriting phone settings
For several device types, there is an option to copy the settings of the Gigaset T300 PRO /
Gigaset T500 PRO directly to the phone via the network without having to change the
settings on the phone.
The prerequisites for this are:
u
The phone has already been autoprovisioned.
u
The phone's HTTP access must not be protected by a user name and/or password.
u
The corresponding SIP account must be stored on the phone's primary line, as Gigaset
T300 PRO / Gigaset T500 PRO only overwrites this line. If the SIP account is located on
another line, Gigaset T300 PRO / Gigaset T500 PRO will create an additional account on
Line 1.
Fax functionality
This must be specified via
Functionality
for ATA adapters used to connect fax machines.
Advanced settings
Important
When operating external phones, several ports in the firewall that protect the local
network from Internet access (not the firewall for the Gigaset T300 PRO / Gigaset T500
PRO server) must be enabled. The following ports are affected: 5060 UDP and 10000-
20000 UDP (for SIP and RTP), 4569 UDP (for the IAX protocol).
NAT
If the phone is not part of the local network,
NAT
must be changed to
yes
to
allow the transfer of voice information via firewall/router.
