On 5/16/24 – Emailed ADG and Doug the pre-existing Corona IP scheme for both voice and data networks and what will be expected to connect everything back up. I additionally provided a detailed layout of the installed rack configuration as it pertains to patch panels, switches, shelves and an estimation of the patch cables that will be needed to connect everything up. All of this was performed as gratuity.

On 6/13/24 at approx. 10a ~ 2p (4hr) visit #1 – On site visit to new Corona office to meet w/ Doug and the TPX installer to help test the phones. The phones came up almost as soon as they got the equipment set up but they kept rebooting, which appears to be as a result of the troubleshooting of the wireless network. Doug had to leave due to an emergency back in Lake Forest and there wasn’t much of anything more I could do. The TPX tech remained on site on the bridge working with TPX and ADG to get this working and will update us via email. No charge, gratuity per initial visit to test and turn up, as provided in the Corona Network Cabling scope.

On 6/27/24 at approx. 9a ~ 1p (4hr) visit #2 – On site re-visit to new Corona office to assist with network troubleshooting where we discovered the phones are still rebooting and this was NOT related to the continued programming while troubleshooting the wireless network which we continued to troubleshoot in addition to the phones and ultimately they could not figure it out. I reiterated the network scheme for the voice to be DHCP serving 172.16.2.X IP address w/ a default gateway of 172.16.2.254 all belonging to access VLAN 100. ADG isn’t convinced the phone we are testing with isn’t damaged or malfunctioning even though it was factory reset and works just fine when taken off the voice VLAN 100 and it connects via 192.168.2.X which is the data network. Additionally the data network can access then phone system (172.16.1.10) as well as the 172.16.X.X networks and devices. This should not be allowed. I explained this as well but not sure ADG fully understood this. We decided to re-convene again next week where Doug will bring an additional phone w/ him to test and prove out whether this one is faulty.

On 7/1/24 at approx. 12p ~ 2:30p (2.5hr) visit #3 – On site re-visit to new Corona office to assist w/ troubleshooting the phone network and why they keep rebooting. Doug had delivered some additional phones of which I set up and joined the conf bridge. We worked on it for 2.5 hours exceeding the original bridge time allotment and decided to reschedule yet another visit because ADG wasn’t able to get the TPX tech nor were they able to figure out why phones when connected to the VLAN 100 they keep rebooting. I suggested they pull configs from other sites like Lake Forest and Livermore to compare. Will coordinate via email for return visit.

On 7/5/24 at approx. 10p ~ 2p (4hr) visit #4 – On site re-visit to new Corona office to troubleshoot the phone network w/ TPX and ADG. Went through all the same patterns of testing and troubleshooting as before and just as they were about to suggest another visit w/ a wireshark another vendor who happened to also be on the bridge started asking some questions, like retrace our steps kind of questions and it turns out someone, even through myself suggesting this early on and at multiple times, it finally clicked that ADG was using the Corona-side voice gateway IP address also as an IP address for a secondary admin access to one of the switches. We had an IP conflict the whole time and the reason the phones were rebooting is the packets were working 50% of the time. Misc clean up and testing but all looks good. Doug inquired if I could help with another visit next Friday to assist w/ desk setup.
