Configuring the traffic class for Voice and Fax data
The traffic class for voice data and fax data is configurable. The configured traffic class is used as additional
routing criterion in the IP routing table.
Mode: Profile VoIP
Configuring IP-IP codec negotiation
This command is only available on the SN4960 and applies to calls between two IP endpoints (e.g. SIP-SIP or
H.323-SIP). It is in mode “profile voip”.
Disabled “codec negotiation” honors the codec lists from each call leg independently, formed out of the remote
and local capabilities. The DSP is inserted into the RTP path to make sure each side can use its codec. The
DSP is transcoding between the codecs of the two RTP streams.
Enabled “codec negotiation” will keep the DSP out of the picture for IP-IP calls and tries to negotiate a com-
mon codec for both call legs.
