IP Phone

[btrain08]

We have some standalone sites (8300/G700) that have IP trunks back to our main office. We are going to be changing the CLANs that we use at the main site for our IP trunks so all the new node-names are created on both ends. Once we change the far and near end node names on each end and want to test. If I have nobody in the remote site to test with.. can I log an IP phone at my desk into those remote call servers to test the calls are going through AND most importantly have clear voice quality? I know the IP phone can log into another call server, but where is the audio path coming from... there or my main site?

You would need to create a voice Vlan that would have DHCP parameters that would cause that IP phone to seek the PBX in the other office for registration.

Assign that Vlan to a port on your network switch, create a DHCP scope for that Vlan (substituting the distant end switch) plug the phone into that port, and you're all set.

Don't forget to add QoS in the WAN routers for the new Vlan.

Here's an easier way I think... You figure out your test phones IP (by either status'ng the station or list registered), and then change your IP-NETWORK-MAP and map that IP to the NR you want to test from. Then change the tenant on your test station to the tenant you're testing from, and you should see the call using the VoIP resource from the G700 being used...

I do this with Softphone, because our hardphones live in the Voice VLAN which is mapped in the IP-NETWORK-MAP screen, where as the softphone lives in the data VLAN, (because its using my laptops IP address) - this is NOT mapped in the IP-NETWORK-MAP...

Yea, but the only issue with using softphone is the audio path is coming from where you actually are and that doesn't help me test the audio QOS across the WAN.

I can log an IP phone into my other call servers with no problem, but I just don't know where the audio is originating.. locally or from the remote G700.

Then I'd create an Automated Attendant in the distant switch. (Remote access would work as well.)

You could dial into the AA, and route a call across the link to your own phone.

I just re-read your question:

If you register a hardphone (by statically inputting the settings on the phone) to a remote standalone S8x00 - just log into that remote switch, go off hook with your test phone and (by using list trace station) see where the dialtone is generating from... How would it generate dialtone from your main switch if it has no relationship with it???

Not sure if this is the best QOS test - but it will tell you where dialtone is originating from and if talk path can be established.

My earlier post was more in reference if you wanted to test calling from a remote LSP/ESS switch...

Get someone to test at the far end.

How about remotely forwarding a phone in the location to your cell...call the extension and trace the call. Check the stats on the trace and talk/listen to your own call.
