I have used Improcom for my business for 4 years and have been extremely happy with it. If I ever needed any voicemail passwords reset, it was done momentarily, and I need resets quite often. Staff is very friendly.
Bandwidth’s Inetwork specializes in offering solutions including Voice (Origination, Termination, and Toll Free), Emergency Services, SMS, SIP Trunking, and UC Trunking. In doing so, the provider is able to extend their services for Local Exchange Carriers, VoIP Service Providers, Voice App Developers, Cable Operators, IP Relay Providers, and Call Analytics. While Voice, Emergency Services, and SMS are handled by Inetwork directly, both SIP and UC Trunking are handled by Bandwidth. With Inetwork it’s easy for users to contact the provider as contact numbers and emails are departmental—i.e. Sales, Emergency Service Outages, and Customer Experience. Also, there are informative resources available to users. These include eBooks for Telecom, Videos, Infographics, Case Studies, and E911 Overview. Pricing varies from service and the industry it is offered to/through.
