IP terminal details
The following table summarizes the events that can be raised by the SRG50. The events and
details appear in the SRG50 Element Manager at
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 SRG50 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 SRG50 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 SRG50 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.
