- Restrictions
- These features are supported on SIP endpoints Only
- For Jabber Softphones, only separate UDP ports can be used. This is because Windows OS doesn’t allow DSCP markings natively (can be fixed by registry tweak or using GPO)
- Prior to this feature, Jabber Client will divide the RTP Port Range received in TFTP File into two splits. Lower half will be used for audio and upper half will be used for video
