TL-ER5120 and VOIP
Hello,
I want to use a TL-ER5120, replacing my orange box on the fiber.
So I connect the ONT to one of the Wan ports of the TL-ER5120, I configure the PPPOE connection with the Vlan835 appropriately. The connection is established properly, everything works. I configure my NAT rule for incoming connections and it's perfect. The only problem is VoIP.
Indeed we use SIP phones. With the livebox, it goes well but with the router, the calls are good but we do not hear our interlocutor.
Obviously I disabled the SIP ALG. But nothing helps.
On the Wan2 I connected a satelite link, and everything works properly. The only problem is that I absolutely want to use fiber for telephony.
Is this problem known? Is the PPPOE connection the problem?
