Mobile SIP Client not working with UC540 while Desktop SIP client working Fine

[sanjay.khurana]

Hi,

I have Cisco UC540 Voice Router. I have configured SIP services into that box to use 3rd party (3cx Softphone) SIP software on Phone / Desktop,

On Desktop Side my 3rd party softphone is working fine no issue while I am using same client on my andriod mobile I am getting error not

SIP/2.0 401 Unauthorized

.

I have captured desktop & mobile SIP registration logs from UC box.

Please help me to understand where I am doing mistake

mobile softphone logs file : mobile_logs.txt

desktop softphone logs file : desktop_logs.txt
