Q2. In H.323 Mode: Cannot hear ring back tone for PSTN caller.

H.323 IP Phone. When it is on Fast Start mode, VIP-2100 will cut

Q3. In H.323 Mode: VIP-2100 cannot keep registering to Gatekeeper after
Gatekeeper restarted.
Answer:
a. Check whether VIP2100
’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.

GK TTL will overwrite the VIP-2100
’s TTL request by using the default
value.

the Register Server TTL will overwrite the VIP-2100
