I have the RP-AX58 repeater (f/w 3.0.0.4.388.23437) and am trying to use it with a Grandstream HT801 ATA connected to the RP's Ethernet port. Outgoing calls work fine but incoming calls fail (line busy).
The ATA has been working fine connected to an RT-AX56U (retired due to being EOL
) configured in Bridge Mode. Likewise, if I connect the ATA directly to the main router (RT-AX86U Pro, f/w as signature) it works fine.
My guess is that a firewall rule somewhere is dropping whatever packet(s) signal an incoming call but I don't know where to look. The ATA works fine with a direct connection so the router's firewall must be allowing those packets through okay. SIP Passthrough is enabled on the WAN - NAT Passthrough page which is the only SIP-related setting I can see.
In terms of configuring the RP, I add it as an AiMesh node wirelessly (i.e. without an Ethernet connection to the router) and set it to prefer 5GHz wifi for backhaul.
The quirky thing is that when I first add the RP as a node (close to the router and nowhere near where I need it), if I run a cable between the RP and the ATA then both incoming and outgoing calls work. However, when I unplug the repeater and put it where I need it, only outgoing calls work from then on.
It occurred to me that I could set the router's firewall to log all packet types and try calling the ATA. The logs should include the incoming call packet(s) but I don't know where to add rules to allow them, assuming I identify them correctly!
Can anyone offer any help or guidance as to where to look, please?
