a. Consult to PABX/PSTN vender to clarify the PABX/PSTN will generate
ring back tone.
b. For Fast Start mode, make sure the far end VoIP end point will have
ring tone generated. For example, a PSTN subscriber calls a VoIP
H.323 Lan-Phone. When it is on Fast Start mode, WG5290 will cut
through the voice path after receive Fast Start Ack. Please make sure
the Far End VoIP Endpoint will generate ring back tone over RTP
media path to WG5290.
c. If you really need WG5290 to generate PSNT ring back tone, please
do the following setting:
- Turn on “local ring back” from “Interface -> Trunk” for each
trunk required local ring back tine generation.
- Disable Fast Start for H.323 outgoing call (set to disable or
H.323 incoming call only.)
Q3. In H.323 Mode: WG5290 cannot keep registering to Gatekeeper after
Gatekeeper restarted.
Answer:
a. Check whether WG5290’s register time to live is too long or not. If yes,
make it shorter from “H.323 -> Register Time to Live”. If we make it
longer, it means it might need take long time to re-register to
Gatekeeper after Gatekeeper failed or restart. If it is very short, will
cause more IP traffic.
b. Check whether Gatekeeper has a preset TTL setup or not. If so, the
GK TTL will overwrite the WG5290’s TTL request by using the default
value.
Q4. In SIP Mode: WG5290 cannot keep registering to SIP Register Server
after Register Server restarted.
Answer:
a. Check whether WG5290’s register IP address, port, user id and
password are correct.
b. Check whether Register Server has a preset TTL setup or not. If so,
the Register Server TTL will overwrite the WG5290’s TTL request by
using the default value.
Q5. WG5290 cannot make a success call.
Answer:
a. Check PSTN trunk ready to work or not. You need to have the
following event generated - “9504: trunk alarm clear (trunk #)”
b. Check WG5290 is registered to H.323: Gatekeeper /SIP: Register
Server or not. You need to have the following event generated - “9503:
H323 GK/ SIP Register [xxx.xxx.xxx.xxx] found & registered”
c. Check the digit manipulation setting is correct or not. Make sure you
have DM put into call flow editor, interface or VoIP.
d. For P2P call, make sure you have the address book setting for dialed
number.
Q6. Cannot hear voice after the calls connect.
