RTP protocol is used for voice calls. Each voice call needs two RTP streams
(one for each way). The first RTP port value must be higher than 1024.
Codec priority
Select a voice codec for audio calls. If your SIP proxy does not offer one
matching audio codec at least, the call will be rejected!
IP addresses
Here set the IP address and IP port for the SIP proxy, VoIP card, NAT and
STUN servers.
o
SIP proxy – IP address and IP port for incoming and outgoing calls.
When you set
SIP proxy IP>GSM
to 0.0.0.0, the gateway will receive
incoming calls from any SIP proxy!
o
SIP registration – IP address of the registration SIP proxy server.
o
NAT firewall – IP address of the used NAT (Network Address
Translation) firewall router.
o
VoIP card / MGCP gateway – required IP address of the VoIP card of the
connected gateway.
o
STUN server – public IP address of the STUN (Simple Traversal of UDP
through NAT) server. The STUN server will give the public IP address of
your IP router. This public IP address will be used in the VoIP cards. The
STUN server is required in case your public IP connection has no fixed
IP address.
o
Next STUN server request – time period between two requests for public
IP information. The gateway will also send request after every system
restart.
Note
The default IP port for SIP signalling is 5060. The RTP range is 8000-8998.
The STUN port is 3478.
In case the gateway is behind the NAT, you have to forward NAT routing
to the appropriate port. Integrated firewalls can also have influence on
VoIP calls!
Tip
In case you have problem with calls (one side audio, no connection, etc.),
check the configuration of all active components (routers) on the VoIP call
route. For easier troubleshooting, we recommend that a network protocol
analyser should be used (e.g. WireShark – www.wireshark.org).
SIP registration
Here set all parameters for registration with the registration SIP proxy.
o
Registration expires – registration validity term.
o
Re-attempt registration – time interval for repeated registration request
in case of registration failure.
o
Registration domain (Realm) – required registration domain.
o
Name – registration name.
o
Username / Password – registration username and password. These
parameters are write-only for security reasons.
