VoIP on Cable ISP using Cisco uBR900 router
Posted on 2004-04-22
I have the above router that is supplied and owned by the ISP. They dont allow me to peek at it and definately not change anything. However they will change if I ask nicely!
OK, my issue is that I am a SOHO using the superb Cisco 7960 VoIP handset (without call manager). This I have connected into the router. All networked PC's (4 off) are connected to a switch which in turn uplinks to the router so everyone has access to the ISP. The reason for this setup is that the Cisco router has only 10mps while the switch has 100mps networking.
Everythng works fine (after much sweat and tears), the Cisco IP phone is set to use G729 codec as we have found the voice quality is better than G711.
The ISP has sold me a 300 / 300 connection.
My question is in two parts.
How can I verify that I am getting what I am paying for? I can use many freebie programs to verify that my download is more or less 300 but I can find nothing tho help me verify that my upload us 300.
Also, is the 10mps router connection affecting the VoIP connection quality? Would I be better asking the ISP to provide a cable modem and use the better connection speed of the switch. They claim that this is not practical as I have a fixed IP which I understand is highly desirable for effective VoIP.
I am asking this question as I have checked the connections using ping plotter and the turnouround reproted by PP seems not to have changed since the upgrade from 300/150 to 300/300 ISP connection.
Sorry to waffle but I guess to get a correct answer you need a detaied question.
