SIP phone cannot register from VLAN
Posted: Sat Jul 01, 2023 2:53 pm
SIP phone --> D-link DGS-1210 switch --> Mikrotik RB4100 --> DSL modem
If SIP (Yealink W70B) is on default LAN, it gets 192.168.88.20 & Registers fine at VoIP provider on Internet via DSL line out
If I make the port on D-link untagged VLAN 21, W70B gets 192.168.21.2 and Registration FAILS (yet full access to Internet from this VLAN exists)
I can even add rule (not needed for normal operation with existing rules below) to explicitly allow forward from 192.168.21.2 and then the log shows:
I cannot see what could be causing it, as for the exercise, I chose the very basic set of rules (none of them stops the communication)
VoiP NAT rules are only needed for the INCOMING calls (so not involved in the Register process)
Any help would be appreciated
