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...

I want to sharpen my day-to-day troubleshooting skills around Twilio Programmable Voice and, in particular, dive deep into TwiML and call-flow logic. The goal is to meet regularly—live, one-on-one—to dissect real customer-reported issues, replay them with sanitized data, and step through practical fixes.

I already work in technical support, so the sessions should feel like an advanced lab where we pull log files, test APIs, and reason through what is really happening on a call. This is ongoing mentorship rather than a packaged course. We can agree on a cadence a...
