Can't receive incoming landline calls after adding a second modem to the home network

[neallfam]

Hi,

Recently added an Asus RT-AC68U to my home network and now I can't receive incoming calls on my landline which is connected into the second modem which is a Telstra Gen 2 Arcadyan.

When you call there is no dial sound and about 20 seconds later it goes to msgbank.

Have read most of the similiar questions here and tried them with little success.

Thanks in advance for any and all help

If you have the WAN port of the Telstra modem connected to a LAN port on the ASUS change the SIP ALG setting on the ASUS.
