VoIP and HP Switches
Posted on 2013-01-25
I need to figure out how to get VoIP phones running over my vlans and I could really use some help.
My “core switch” is an HP v1910-24G-PoE (365W).
On this switch there is:
vlan 1 – 192.168.0.0/24 (untagged 1-21,23-24) (default vlan)
Vlan 2 – 192.168.5.0/24 (untagged port 26)
Vlan 3 – 192.168.4.0/24 (untagged port 27)
Vlan 4 – 192.168.3.0/24 (untagged port 28)
Vlan 5 – 192.168.2.0/24 (untagged port 22)
The VoIP PABX (10.5.13.146/28) is connected to a mikrotek unit (10.5.13.145/28) and it also has an ip of 192.168.0.238 (they are on port 18 and 19).
At the other end of each of the vlans there is another HP v1910-24G-POE switch configured as follows:
192.168.5.1/24 – default vlan gw 192.168.5.254 (on the “core switch”)
192.168.4.1/24 – default vlan gw 192.168.4.254 (on the “core switch”)
192.168.3.1/24 – default vlan gw 192.168.3.254 (on the “core switch”)
192.168.2.1/24 – default vlan gw 192.168.2.254 (on the “core switch”)
The PABX is an Alcatel-Lucent OmniPCX and all phones are Lucent 4018 IP Phones. The phones are set to work on vlan 7. I have no access to the mikrotek unit or the PABX.
If I plug any of the ip phones directly onto the 192.168.0.0 range, they detect the PABX and work, no problem. If I move the phones to anyone of the vlans, they cant connect to the PABX.
I need to be able to deploy these phones to the various areas around the network without having to “drop” the current vlan setup. I really don’t want to run a flat network.
Where do I start? Any help would be greatly appreciated.
