IP terminal details
The table IP Terminal Details on page 84 summarizes the events that can be raised by the SRG.
The events and details appear in Element Manager at Configuration > Telephony > Sets > Active
Sets > IP Terminal Details.
Periodic retries may result in the same condition being detected over and over again. In these cases
the SRG state machine uses flags to indicate that a given event has been logged.
One-way or no speech paths Signaling between the IP telephones and the SRG uses UDP port 7300.
Voice packets are exchanged using the default RTP:
Source port (output filters)/Destination port (input filters): 28000 through 28511
for the VoIP gateway. Output filter Destination IP is set to ALL. Input filter
Destination IP is the IP address of the SRG local gateway.
Source port (output filters)/Destination port (input filters): 5200 - 5201 for the IP
telephones. Output Destination IP is set to ALL. Input filter Destination IPs are
the IP range for all IP telephones (behind the firewall) in Normal mode.
Source port (output filters)/Destination port (input filters): 51000 - 51184 for the
local mode IP sets. Destination port (output filter) and Source Port (input filter)
are set to ALL. Output Destination IP is set to ALL. Input filter Destination IPs
are the IP range for all IP telephones (behind the firewall) in Local mode.
UniSTIM signals use specific source and destination ports:
Output filters: Source port, 5000; Destination port, 4100, 5100, 7300. Output
filter Destination IP is the IP address of the main office TPS.
Input filters: Source port, 4100, 5100, 7300; Destination port, 5000.Input filter
Destination IPs are the IP range for all IP telephones (behind the firewall) in
Normal mode.
If these ports are blocked by the firewall or NAT, you will experience one-way or
no-way speech paths.
Firewall note: If the firewall filter is set to Pass Outgoing and Block Incoming
Except IP Phones, this allows only IP telephony registration traffic through, but
blocks all other traffic, including H.323 calls on this interface. You must still
specify an H.323 rule to allow IP call voice traffic.
