[Freeswitch-users] Cisco 7975G and XML options for G722

[Brian West]

Cisco 7970 and the G.722 codecThe G.722 codec is disabled by default  
on the 7970G phone.

- To enable the G722 codec, add the following line inside of the  
<vendorConfig> context:
        <g722CodecSupport>2</g722CodecSupport>

- Add the following line within the <device> context:
        <advertiseG722Codec>1</advertiseG722Codec>

On a config generated by CUCM 6, the 'advertiseG722Codec' context  
usually appears on a new line following the <encrConfig /> context.

- It is also useful to add the following lines inside of the  
<vendorConfig> context, but these are purely optional:
        <headsetWidebandUIControl>0</headsetWidebandUIControl>
        <handsetWidebandUIControl>0</handsetWidebandUIControl>
        <headsetWidebandEnable>0</headsetWidebandEnable>
        <handsetWidebandEnable>1</handsetWidebandEnable>
