To stay competitive, an organization’s high-performing employees need flexibility, to maximize their productivity without being tied to a desk. Plus, as a business, you must be able to maintain and protect sensitive company data while ensuring that your employees are fully accessible even while on the road. Employees often use personal devices for business transactions while on the road, which the company has no visibility of. These road warriors need a viable solution that gives them the ability to use their personal phones yet remain connected to the corporate communication system, enabling them to leverage business information with every call. In addition, businesses frequently lose components of the client interaction history when customers are contacted outside of their corporate phone system. Businesses need a solution that offers insight into all employee / client interactions, even those conducted while their employees were on the road. The solution is ESI ePhoneGO2™. Having the ePhoneGO2™ application on the iOS smartphone presents a user experience that mirrors the functionality of the ESI desktop phone, allowing employees who are “on-the-go” to make and receive business calls from anywhere using their personal devices, while still maintaining a single office phone number and voice mail. This also eliminates the need to publish anyone’s private mobile number to clients! Features – Receive calls on your Mobile device which were placed to your Office phone number – Make outgoing business calls remotely which appear to have been placed from your office – Calls made with ePhoneGO2™ will broadcast your office Caller ID, (not your personal phone number). – Establish one-to-one Video calls with other ePhoneGO2™ users. – Established voice-calls can also be upgraded to Video calls with other ePhoneGO2™ users. – View the Corporate directory with availability status of your contacts. – Create a list of frequently called users from the company directory or your phone’s personal contacts. – Established messaging sessions (SMS or IM). – Transfer calls (blind or supervised) as you would do from your desk. – Record calls from your mobile phone. – Turning Do-Not-Disturb ON or OFF for the mobile device. This allows you to pause alerting while you have your desk phone available). – Call routing options fully sync with your platform – Notification of new voicemail messages. – Make calls over WiFi or 3G / 4G / LTE / 5G, regular data rates apply IMPORTANT ESI ePhoneGO2™ for iOS requires an active account on the ESI Cloud PBX™ **Voice quality is highly dependent upon your WiFi or 3G / 4G / LTE / 5G network bandwidth** Warning for 3G / 4G / LTE Usage Some mobile carriers prohibit or restrict the use of VoIP calls over their networks and may interfere with, block, or institute fees for calls made over their 3G / 4G / LTE / 5G data networks.

It sounds like people are talking through a tube. And there is always a little static feedback ### 1/5 — Phone and text *2026-04-14, version 21.12* Never works ### 1/5 — Too difficult to use *2026-02-26, version 21.12* I do not like this phone ### 2/5 — Messages Disappeared *2025-09-05, version 21.8* The text messages section on the app just disappeared, even though when I open the app it still shows them quickly at the top. Now I can’t find them though! Please fix ASAP! Also texts don’t notify my phone when they come in, so that’s really unreliable & frustrating!! ### 1/5 — Still does not, and never worked *2024-12-04, version 21.7* To this day, the desktop version still does not properly work and they have no solution ### 1/5 — Constant issues *2024-10-07, version 21.7* Texts almost never come through unless I have the app open on my phone. Every other app I have sends push notifications just fine. Constantly having issues sending texts with any kind of media as well. Pictures, links, etc will not work for my customers. ### 1/5 — Not easy to use at all *2024-07-29, version 21.7* Too may steps to take to get things done. ### 3/5 — Contacts *2024-07-24, version 21.7* I was trying to save contacts from in the app, I have it on my personal phone. In order to save them, I have to save the numbers in my personal contact list on my phone and sync the contacts in my contacts list. I’m still trying to figure out how to get phone calls while I am away from the office after hours. The instructions aren’t very clear on how to do that. Other than that, it’s a good app to have for work! ### 1/5 — Rating *2024-06-07, version 21.4* Transfer calls don’t work well and say failed ### 1/5 — Trash *2024-05-07, version 21.3* Audio quality is terrible, if you don’t use it because of this for a short time it will stop forwarding calls to you due to inactivity. So far I haven’t found a single thing positive about this app and system. ## Frequently asked questions about ePhoneGo2 ### What does ePhoneGo2 do? ePhoneGo2 enables employees to use their personal smartphones for business calls, mirroring the functionality of their ESI desktop phone.
