I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT.

My Squarespace site is fully built; I simply need the domain to resolve correctly without moving nameservers away from Cloudflare. I want a specialist who can help guide me to update my Cloudflare dashboard, add or adjust the required A and CNAME records that Squarespace specifies, wait for propagation, and confirm the green-light connection inside Squarespace. Key points
 • Cloudflare must remain the authoritative nameserver – please do not touch that setting. • Only A and CNAME records are involved; no MX or other entries need to change. • The Squarespace side is ready, so the task ends when the “Connected” status appears and the site loads over both root and www. Please let me know your estimated turnaround and any brief details you need to s...

My security cameras stopped showing live video and recorded footage on the monitoring app. The wiring and power seem fine, so I’m convinced the problem sits on the software side—likely a mis-configuration or corrupted firmware. I need someone who can jump in quickly, diagnose the software fault, and get every camera streaming and recording again without wiping my existing footage or settings. You should be comfortable with typical NVR/DVR interfaces, remote desktop tools, and updating or rolling back firmware when necessary. Once the feeds are restored, I’d like a short explanation of what went wrong and the steps you took so I can avoid the same outage in future.
