Mode:
Profile VoIP
Configuring the transparent-clearmode codec
To be compatible with RFC4040, transparent-clearmode was made available as a codec in the voip profile. The
codec can be used if exclusively packetisation and no coding/decoding is needed.
Mode:
configure/profile voip
Configuring the Cisco versions of the G.726 codecs
The Cisco versions of codecs are listed in the previous section as separate codecs with their name ending in –
cisco. SmartWare supports four Cisco codec versions:
g726-16k-cisco
,
g726-24k-cisco
,
g726-32k-cisco
,
and
transparent-cisco
. Three of the codecs are variations of G.726, the fourth is
transparent-cisco
.
The
transparent-cisco
codec provides full compatibility with Cisco’s
clear-channel
codec used for transmission of
Unrestricted Digital Information over a VoIP (SIP or H.323) network.
Cisco does not use the standard ITU G.726 version of G.726, instead it uses the ATM AAL2 version.
All supported Cisco codecs are available in profile voip.

The next table indicates the method of configuring a Cisco-variant codec as the most preferred codec. This
example sets the ‘transparent-cisco´ as number 1, the most preferred.
