For most dell systems, idrac, bios, CPLD, raid controller, nics, all have firmware updates that should be applied. Power supply sometimes, not usually necessary.

But R720, don’t do it. T620 don’t do it. R620, don’t do it.

I haven’t had any issues before or after that cursed xx20 generation.

DONT DO IT!

Most r720’s have a bad flash chip so the idrac update will fail, and you’ll have 100% fan speed and a nice idrac init failure that requires keyboard intervention at every boot up. Mobo replacement is the only fix once your there.

Skip bios, and idrac updates at all cost!

Raid controller and NICs can be safely updated though.

T620 - died during idrac update. R720 - died during idrac update. Customer R720 - died during idrac update.

A few times it happened under warranty and the mobo was swapped out, but r720 is no longer warranty eligible. Not worth the risk, basically 0 benefit too if the system is working today.

I ran FreeSwitch with a signalwire sip trunk. I don’t think there’s much cheaper than that. Pay as you go, less than a penny per minute. Only monthly fee is holding onto the numbers you want, each number is like $0.50 per month.

But installing and maintaining it is a challenge for even good sysadmins.

I’d go with 3CX or a similar all in one provider if I had to make the call.

Also, use a good USB headset and a soft phone on your computer instead of that old cisco handset. Get away from handsets ASAP. They are the most expensive thing, vendor support dries up fast, and the audio codecs go stale. Firmware vulnerabilities emerge, compliance requires you to update them, so every 5 years, new handsets for everyone. It’s a joke. USB headset or a good USB speaker phone will work with any system, until they physically break. 3cx has soft phone clients so handset isn’t needed at all.
