which you expect VoIP calls. Verify that the codecs which
have been entered in the
VoipCompression
parameter
match the peer’s codec. To look up the codec offered by
the peer, you need to run a layer 2 / layer 3 trace.
|
In the case of an outgoing call, set
VoipDirection=Out
or
VoipDirection=IO
. The
VoipPeerAddress
parameter
must contain the IP address to which you send VoIP
traffic. The
VoipIpMask
parameter is not needed. Again,
the
VoipCompression
parameter needs to match the
peer’s codecs.
|
In all cases, ensure to put the profile name in square
brackets.
|
In the following example, the gateway receives a call
from the IP 195.4.13.14. There is only one VoIP profile for
incoming VoIP calls in the gateway’s
route.cfg
file. The
VoIP profile’s
VoipPeerAddress
parameter is 195.4.13.0.
The
VoipIPMask
parameter contains the value
0xfffffff8
which translates into the subnet mask
255.255.255.248. This means that the IP addresses
195.4.13.0 to 195.4.13.7 can send calls. The IP address
195.4.13.14 which actually sent the call is not inside this
range. The call is thus rejected by the gateway.
