Voice Over Internet Protocol | VOIP

What is VoIP (voice over IP)?

VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet. If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company. Some people use VOIP in addition to their traditional phone service, since VOIP service providers usually offer lower rates than traditional phone companies.

How does VOIP work?

VoIP technology enables traditional telephony services to operate over computer networks using packet-switched protocols. Packet-switched VoIP puts voice signals into packets, similar to an electronic envelope. VoIP packets can be transmitted over any VoIP-compatible network, such as a local area network (LAN).

OnSIP on Your Cell Phone

In order to make and receive phone calls when you are not in front of your computer, you can use a softphone app on your cell phone in parallel of Odoo VoIP. This is useful for on-the-go calls, but also to make sure to hear incoming calls, or simply for convenience. Any SIP softphone will work.

On Android and iOS, OnSIP has been successfully tested with Grandstream Wave. Also When creating an account, select OnSIP in the list of carriers. You will then have to configure it as follows:

  • Account name: OnSIP
  • SIP Server: the OnSIP ‘Domain’
  • SIP User ID: the OnSIP ‘Username’
  • SIP Authentication ID: the OnSIP ‘Auth Username’
  • Password: the OnSIP ‘SIP Password’

Aside from initiating calls from Grandstream Wave on your phone, you can also initiate calls by clicking phone numbers in your browser on your PC. This will make Grandstream Wave ring and route the call via your phone to the other party. This approach is useful to avoid wasting time dialing phone numbers. In order to do so, you will need the Chrome extension OnSIP Call Assistant.

Warning :- The downside of using a softphone on your cell phone is that your calls will not be logged in Odoo as the softphone acts as an independent separate app.
