Connect to the WLAN IP Telephony Manager 2245 95
IP packets (the packets use a nonstandard protocol number), there can
be no Layer 3 routing in the path. Therefore, the wireless handsets and
WLAN IP Telephony Manager 2245 units must be in the same logical
subnet.
•
RTP packets between the wireless telephone and the WLAN IP
Telephony Manager 2245 always contain 30 ms worth of voice, no
matter what is configured on the Call Server. The WLAN IP Telephony
Manager 2245 repackages the RTP packets to conform to the size that
is configured in the Call Server. This provides more efficient use of the
available Radio Frequency (RF) bandwidth at the expense of slightly
increased jitter and latency.
•
The WLAN IP Telephony Manager 2245 is configured with a maximum
allowable number of simultaneous media streams on a single AP.
The WLAN IP Telephony Manager 2245 keeps track of the number
of media streams on each AP and blocks calls to and from a wireless
handset that would exceed the configured capacity. For more
information about call blocking, see “Call blocking” (page 73).
A keep-alive packet exchange runs between the wireless handset
and the WLAN IP Telephony Manager 2245 every 30 seconds. If the
wireless handset detects that the WLAN IP Telephony Manager 2245 is
unreachable, the wireless handset resets itself and attempts to reestablish
a connection with other WLAN IP Telephony Manager 2245 units.
Configuration tasks
The following are the tasks required to configure the WLAN IP Telephony
Manager 2245:
1. “Connect to the WLAN IP Telephony Manager 2245” (page 95).
2.
“Configure the network” (page 97).
3.
“Configure the WLAN IP Telephony Manager 2245” (page 100).
4. “Change the password” (page 102).
In the initial configuration of the WLAN IP Telephony Manager 2245, the
IP addresses and the maximum number of active calls per AP must be
configured. Later, you can use Telnet to configure the IP address of the
TFTP Server where the software files are located and the hostname.
Connect to the WLAN IP Telephony Manager 2245
The initial connection to the WLAN IP Telephony Manager 2245 must be
made through a serial connection to establish the WLAN IP Telephony
Manager 2245 IP address. After the IP address is established, connection
to the WLAN IP Telephony Manager 2245 can be done through the
network using Telnet.
