I’m trying to setting up a RUT241 between my ISP modem/router and my LAN, using it to keep internet working with SIM failover backup. The only problem is that my IP phones don’t work.
My network infrastructure is:
- Internet connection
- Aethra BG
- RUT241 (where I think I should put it)
- LAN with IP phones and PCs
Failover feature works perfectly and my IP phones are able to register both under WAN and mobile connection but:
- they don’t ring when there are inbound calls
- when they call outside and the receiver picks up, the IP phone doesn’t begin the conversation
I don’t know if I’m fully understanding the functioning of the RUT241. Shouldn’t I be able to keep the phones alive passing through the ISP router when in WAN and passing through RUT241 when mobile connection is active?
Thanks to everyone who could help.
