By doing a Traceroute command to sip.crmdomain.com and submitting the results of this to us we are able to examine the traffic on your broadband line and see how this is being routed and see if there is any congestion on the line which can result in packet loss - therefore affecting call quality. 


Packet loss is the biggest issue on call quality – we use a UDP packets to transmit the data between us and if a packet of data arrives out of sync then it is dropped – this is to ensure the real-time of the communication.


Traceroute is a command which can show you the path a packet of information takes from your computer to one you specify. It will list all the routers it passes through until it reaches its destination, or fails to and is discarded. In addition to this,it will tell you how long each 'hop' from router to router takes.


The Traceroute will start with traffic going through your router - onto your Internet service providers (ISP) routers and then onto other networks before going onto the VoIP sip platform.
