This is a little hard to explain, but her it goes.
We have a 450G running 5.11 RouterOS, ports 2-5 are grouped in to a Bridge, and I have
vlans attached to that (5 = voice, 11, 22 for the work benches). These are trunked
to a Dell 3548P switch.
Routing works fine between all subnets using TCP. However when I want to use
an IP phone either on the default network (bridge) or on one of the other vlans 11 or 22,
I get audio that can travel to vlan 5, but not back out. However, this sometimes
“just works” at times.
The phones are Iwatsu Icon series, UDP ports used are 50002/50003 from the phone side
connecting to the same ports with another phone. They connect peer to peer if the same
type of phone.
When it is not working correctly, I run Torch on the 450 and notice that the audio
is being sent from a phone on vlan 5 but also shows it using port UDP/2005 as
well as being on vlan 49157?
I have a screen shot attached, if you need me to run specific test to help root
the issue or provide more information I can do that. This is important to figure
out for us as we use Mikrotik routers for our customers as well.
