Hi Team,
Greetings for the day.
My name is Sudhir Aggarwal and currently I am working as Network Engineer at Cisco TAC.
I have a networking profession in Cisco VoIP (Voice domain) and total experience of more than 3.6 years.
I have completed CCIE in collaboration domain.
As far as your issue is concerned, there might be the issue with call signalling as the error you are getting is Client error (408 request timeout).
Need to check call signalling.
Hope to hear from you soon.
Regards,
Sudhir Aggarwal
