I have been using Ring Central for years now and could not be happier.
Using JustCall. Great customer service. A lot of really good features and good integration with Pipedrvie - word of warning - their Power Dialer sucks
XBP. Best phone system I have seen for the price. It's a fraction of the cost of every other provided we looked into and the don't limit any features or nickel and dime you do death for add-ons. It's a full featured PBX replacement with everything. However, they recently got acquired by Broadvoice and I hear they don't offer the same plans we are on anymore.
I don't know if it qualifies as Voip but I use Google Voice with my US cell phone to do business in the US without added roaming or other fees from my current base in Greece. I had to set up Google Voice in the US before leaving, you can't get a number if you are out of the states. It's great, customers call my US cell number and I call their landline or cell number just like I was in the states, no country codes, no roaming, no per-minute fees for either party. If I call other locations in Europe I have to pay a few cents a minute which I do occasionally and that is through Google Pay, not through my cell plan.
We use Mitel. It’s a love/hate relationship. Love the lack of administration, infrastructure, provisioning work, and cost relative to hosting it on-prem. But, we have problems with it from time to time for no reason (no changes). It will stop working, stop ringing, the backend will go down, weird config changes that we did not request, and the like. We are still with them, but we are not “happy” overall. Even though they are a new-dangled cloud provider, they use really old software. Our voice recording app, for instance, refused to run on Windows 7 and above for a long time. XP only, seriously. And this was only a couple of years ago. We were already on Windows 10 and had to set up a VM to run it. That wasn’t supported but it did work until they updated it. No excuse for that.
I would like to see RingCentral work with Pipedrive both phone and texting options.
I've been using Vonage for personal / home office use for over 10 years now and am perfectly happy with it - as long as I have internet, it works like a charm. I've taken it with me to Mexico for 7 weeks, plugged it in, and had my phone like normal.
RingCentral also and very happy.
Yes and I use JustCall.io
We use Kixie because most of the business we do is on mobile phones and all the other apps we tried are really meant for desktop users. They integrate with Pipedrive but we are not happy with the integration as the contacts don't merge. The other reason we use it is because our CEO used to travel A LOT prior to covid and we needed a transcription service. Kixie is the only one that integrates with gong and pipedrive that has an ok mobile app. I'm trying to get pipedrive to get their caller feature to integrate with gong or to have transcription so we can stop using kixie.
We use Microsoft Teams for calling and automated phone attendant. Works well from desktop or mobile phone. Haven't tried to integrate it with Pipedrive.
