Administrator Guide – AzaCall200 VOIP Multi-Protocol Gateway
Both VOIP and Line
LEDs are blinking
To ensure best service offering, user Service Provider may provide
user automatic upgrade of gateway device’s firmware through
user broadband network.
During firmware upgrade, the VOIP and LINE LEDs will be
blinking simultaneously.
It takes a few minutes for the upgrade to be complete. DO NOT
power off the gateway device while the LEDs are blinking. It
will stop blinking when done, and user VOIP service will be
resumed.

If you cannot hear the remote party during a call, it is possible that
your AzaCall200 is behind a firewall or NAT router.
If the AzaCall200 is behind a NAT router log into the web
interface of the AzaCall200 as ‘supervisor’ and ensure that
you have a Session Border Controller (Outbound Proxy) set
in the SIP menu [
refer to section 5.14.4
] if you or your
service provider are using a Session Controller
or
check
STUN settings to ensure that the proper routable IP address
is set in the NAT Address field [
refer to section 5.14.9
].
If the AzaCall200 is behind a firewall, check the above
process for NAT and also ensure that following
incoming/outgoing ports are open:
•
13456/UDP (RTP)
•
5060/UDP (SIP)
