DHCP VOIP Without VLAN

Empty Set
Hello, We're in the beginning stages of rolling out IP phones and we want to use a different DHCP scope for phones as opposed to workstations. Our office is only roughly 40 users so I don't think VLANs are worth the effort so I wondering if someone with more knowledge on Sophos and just the process in general could provide some guidance to if this is possible and if so how to proceed. Thanks

    As explained above you should really consider to DO choose for VLAN's. It's really not that difficult and most switches nowadays fully support it and can also automatically put your phones in the right VLAN no matter to which switch port you connect them (Using what's called Voice VLAN where the switch looks to the MAC-address (OUI-part) and based on that places the phones into their own VLAN).

    Also the built-in switch doesn't have to be a problem; we have an Avaya system and there the computers connected to the phone's switch will get the proper VLAN (which is different from the phone's VLAN itself). Also we don't really have any problems with the built-in switch on the phones other than that most of our phones have a 100Mbps built-in switch.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
