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. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

We need a web-based platform to manage and monitor proprietary devices installed across Italy. Each device has a unique progressive code (001, 002, etc.), a dedicated phone number, installation details, and contact information. Devices send a phone call every 72 hours as a heartbeat signal. The system must detect these calls, determine whether devices are communicating correctly, and flag devices that stop communicating. Devices can also generate alarm calls to different numbers, which must be recognized and logged. In case of missing communication or alarms, the platform must send automatic email notifications to an internal email and daily summary emails to the on-site contact. Each device has an annual call center contract. About 30 days before expiration, the system must email the...

I need UAE number for VOIP call inbound and outbound call, do you know which provider is best for this ? or you can provide us this service ?

I need an experienced telephony engineer to bring up a new IVR on our Asterisk-based server that will answer calls coming in on both a SIP trunk and a PRI. The core requirement is a clean, dependable call-routing tree—callers should reach the right destination every time—with call recording and basic, built-in reporting turned on from day one. Environment • Linux box already running Asterisk (remote SSH available) • One SIP trunk + one PRI (credentials and circuit details ready) Scope of work 1. Configure the IVR in Asterisk, activate call routing options, and confirm that both trunks follow the same logic. 2. Enable call recording for all menu paths, store files locally in an organised directory structure, and verify playback. 3. Turn on the stock call‐...
