Hello
I have great experience in VOIP(SIP, RTC)
VoIP for service offers a huge range of benefits including
Click to call
Home working
Flexible call routing
Colleagues on-line
Active Directory
Hosted service with full resilience and 24-hour system management
Cost reductions through a minimal capex investment and low cost of ownership
Make calls over the internet at dramatically reduced rates.
Wide range of PBX features including caller display, call waiting, call transfer, voicemail, last number redial and three-way calling
PC Client software providing on-screen multimedia phone capability, including desktop video-conferencing, presence, instant file transfer and web push.
Variety of call management options including call routing, call screening and call logging
A VoIP telephone number that travels with you wherever you go, with your account accessible via any web browser worldwide.
SIP Trunks can be used to complement, or entirely replace existing ISDN or analogue lines, as well as bring many of the other benefits associated with IP, which can implement a gateway solution to enable SIP Trunking without any changes to your existing hardware.
SIP Business benefits
Considerably reduce your monthly line rental and call charges
Add resiliency to an existing PBX
Add call capacity without increasing the number of fixed lines
Thanks
