Hi,

You can check the QOS settings to make sure the signaling traffic is marked with correct COS & DSCP value and is given adequate bandwidth. If its only specific to 7841 and other models are working fine then can you check the bug below:

Hi Assem,

Thanks for your reply Aseem. Active firmware of Phone is 10-3-1-12. Since 10.3 (1) is mentioned as known affected version let me try with firmware upgrade and update you.

Thanks in Advance...
