Cisco UC540 SIP Trunk Setup

I have a Cisco UC540 on-site and a live SIP trunk supplied directly by our ISP. All the registration details—SIP username, password, registrar, codecs, DID ranges—are already in hand; what I need is a specialist who can jump in remotely, register that trunk on the UC540 and make sure both inbound and outbound calls flow cleanly.

Here is how I picture the engagement:

• Remote configuration through CCA or pure CLI, whichever you are most efficient with.
• Correct dial-peers, voice class codecs and translation rules so our full DID block reaches the right ephone-DNs and outbound calls present the main number.
• Basic feature verification: two-way audio, multiple simultaneous calls, caller-ID, and voicemail routing to CUE.
• A brief hand-over showing the commands you touched or a saved CCA config file for our archives.

Once test calls in and out are solid, we are done. If you have recent experience with UC500 series or similar CME builds, this should be straightforward work. Let me know your availability and the remote method you prefer (AnyDesk, SSH tunnel, etc.), and we can start right away.
