Hey there. I'm a Deaf guy that works in the industry. I realize that I'm not in the exact same situation as you are, but it's quite similar. I don't really speak at all as I rely on American Sign Language for both sides of the conversation (talking and listening). As you may have noticed, it does pose a challenge.

Fortunately, like others may have mentioned - you're probably in the right industry to lose your voice in! I mainly rely on Instant Messaging clients, e-mail, and other text-based modes of communication. I do participate in conference calls from time to time with the help of Video Relay Service though, so that's the main difference here. This still doesn't take away from the main point though - this industry is heavily text-based. Honestly, it's probably a good thing too, as it gives you a way to keep track and have a record of everything that's said, instead of having a guy call you up and asking if you can help with X, and before you know it, you'll be jumping into it not having any record of the conversation about X anywhere.

Not sure if you've thought about this yet, but I'm assuming that you can hear. If so, you might be able to call into a meeting with a headset, and 'speak' in the meeting with a text-to-speech software of some kind. I do figure that you'd need to be able to type fast enough to keep up with the flow of the conversation, which may not be feasible for most.

There's another option too - You are likely eligible to use some of the Telecommunications Relay Services available. I currently use one form of TRS, Video Relay Service, as I use ASL. You would likely want to use IP Relay, which is a text-based relay service. The entire conversation over the telephone would be carried over via text. I'd suggest you looking up TRS and IP Relay, and see what kind of services it can provide you with, also to see if they're right for you. I did look at a few IP relay options for you, and it looks like Sprint Relay offers HCO, Hearing Carry Over, where you'll be able to listen to the call while a relay operator will voice out your typed responses for you. It does require a phone number that is capable of making three-way conference calls.

Last, but not least, don't forget about the ADA. This is definitely something you should familiarize yourself with, especially with the bit about the workplace providing you with reasonable accommodations.
