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.

 

 

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.
