I have an older ATA phone on may desk that is plugged in to the ATA port on our Fritzbox 7490. As well as that we have 3 Yealink VOIP phones around the house connected to a basestation. When we receive a phonecail only the ATA phone rings or responds to the call. The Yealink VOIP phones do not see it at all, don't ring and can't answer the call. Despite that they will make outgoing calls with no issues AND with the ATA phone unplugged from the Fritzbox respond and receive calls just fine. Does anyone know if or what the setting might be either on the Yealink settings or maybe in the Fritzbox ones to get the VOIP phones to see incoming calls with the ATA phone plugged in to the Fritzbox ?

check out the Telephony settings in the fritzbox and look under devices in the sub menu and check if all phones are listed and then check each phones setting under edit and see if all phones are set for incoming calls etc, you can add phones here as well.

Common sense is not as common as you think.

The symptoms you describe are those of a SIP device (the Yealink base-station) which is not successfully completing "registration". Ie, it can make outbound calls no worries, but the SIP server doesn't know how to find it for inbounds.

If your ITSP is 2talk, try changing the SIP registration port in the Yealink base-station to use port 50600 instead of 5060 - this will bypass the normal port which may already be claimed inside the Fritzbox's NAT engine for the internal ATA and therefore not being passed through cleanly for the downstream Yealink.

So you are using the same SIP account on both Fritz and Yealink???

A phone engineer friend found the answer.....There's a feature on 2Talk called a shared line which is covered here - basically you need to add a xxxxxx-1 to the VOIP ph number and all the phones work

How do the yealink phones connect to voip? If the router is soaking up the voip ports and dealing with voip request it may not allow others in. Where is the voip server? We use 2Talk, and each device connects to their hosted phone exchange. There were some issues around logging in as the same user, we had to get around when they were on the same ip address. QOS, port forwarding, UDP forwarding etc all can get messed up on the firewall stopping your voip phones.

Dealing with voip - i have been bitten many times using the internet router to also do voip. Heat and performance were the main issues. So I split the voip router / ata functions away from my internet router. It may be better now days if you spend good money but once bitten twice shy. try not using the fritz as an ATA server.
