Routing to a Clearmode destination

CCXML applications can create an outgoing call using a clear channel media stream for video calls. You can create a routing rule to specify that the outgoing SIP call should only supply the Clearmode audio codec in the SDP. If not set, the SIP call will not include the Clearmode audio codec.

The Clearmode audio codec complies with RFC 4040, RTP Payload Format for a 64 kbit/s Transparent Call.

Follow these steps to route outgoing calls to a Clearmode destination:

Step

Action

1

Access the Vision Console, as described in Accessing the Vision Console.

2

Click Resources in the Configuration menu, and enable clear channel.

3

Click Gateway profiles in the Provisioning menu. The Routing profiles configuration page with the default profile is displayed.

4

Create a new profile for clear channel mode. Click Clone to make a copy of the default profile and modify it.

Edit the profile name (for example, call it clearmode-out) and profile description in the General section of the profile page.

For information, see General routing profile parameters.

5

Edit the profile and set Outbound Protocol to Clearmode in the General section. Update other parameters as needed. Click Submit.

6

Click Gateway routes in the Provisioning menu and update the profile association for the clear channel routing rule.

For example, the following routing table entry routes outgoing SIP calls in clear channel mode:

ID

Profile

Incoming Called party

Incoming Calling party

Outgoing Called party

Outgoing Calling party

1

clearmode-out

sip:(2111)@.*

sip:(\d+)@.*

sip:$1@10.3.6.1

sip:$1
