Example: Selecting an ISoIP CODEC
The following example shows how to use the g711Alaw64k (64kBit/s) codec as default voice codec
for the ISoIP gateway with 20 ms for the length of transmitted RTP packets.

30.3.3 Configure used Codec for an H.323 Connection and Enable Fast
Connect
The codec used for an H.323 connection could be set in the H.323 gateway as well as in the H.323
interface as follows. In the H.323 gateway a list of all possible codecs is defined. In the H.323
interface one codec of those listed in the H.323 gateway must be specified. The actual codec used for
the H.323 connection depends on whether fast connect is used or not as illustrated in Table 30-1.
A side (outgoing)
B side (incoming)
With fast
connect
1. If present SmartWare sends codec list
in gateway
2. If present SmartWare sends codec
specified in interface as first codec
(preferred) plus the codecs specified in
the gateway
3. If present with tag 'exclusive'
SmartWare sends only this codec.
N.B.: The codecs specified in the
interfaces must also be present in the
gateway codec list.
1. SmartWare selects the first codec from
the incoming codec list which is present in
codec list in gateway; the Session Router
then selects the interface which contains a
codec that matches the selected codec; the
selected codec is used for the bearer
channel.
2. If no interface matches incoming codec,
SmartWare chooses the interface with no
codec specified; the selected codec is
nevertheless used for the bearer channel.
3. If no interface matches incoming codec
and if no interface is present with no codec
specified the call is rejected.
Without fast
connect
1. SmartWare sends codec list in
gateway; codecs specified in interface
(preferred or exclusive) are without
1. SmartWare selects the first codec from
the incoming codec list which is present in
codec list in gateway; SmartWare chooses
