In our network we used several ONT Huawei models. But with one model HUAWEI-EchoLife HG8245 / V1R003C00S205 we have the following problem. When connecting to this device in the POTS ports of the two phones. From the first port we can not call to the second and from the second port can not call to the first port. On the other ONT Huawei devices, there is no such problem. Earlier we had set OpenSIP and this device did not have a problem.
The problem is likely in the configuration because it works at the default settings.
In the past I ran into other devices/PBXs that can't handle the fact there is an outgoing/incoming call with the same callid. You could try the topoh module (with modparam("topoh", "mask_callid", 1))
Beware that it might introduce other problems in some calls scenarios, my prefered solution is to route the call to a b2bua (asterisk) when I detected hairpinning.
