I'm on Vodafone fixed landline & fibre broadband service plan. the modem is vodafone ultra hub. connecting the home phone to one of the voip port in the modem to get the landline phone service through voip. login into the modem web config page, check the phone service configuration, it is sip based voip service.
is it ok to connect a sip phone (not home phone) to the modem (e.g. to the LAN port), and configure the sip phone with the information of the modem phone configuration, to get phone service through voip?
there is only one landline number under this plan. in order not sharing the same landline number when people living here make outbound calls, can set up a PBX server and/or configure vlan to achieve this purpose. has anyone get this working already or have better approach?
thank you very much.
