I noticed that the router has VLAN 400 for VOIP and the ONU has FXS PON that people can call to the caller id such as +6012345678, I wonder VOIP VLAN 400 can able to do that also or not (can call outgoing/receive incoming calls through +6012345678) instead of using FXS through ONU PON (Huawei-HG8240H-ONT)?
IMHO, the VOIP that I gonna use is Grandstream GXP1450.
Hi @MarHazK ,
I am afraid i dont have any experience or knowledge about this one. Judging from your questions, it is like you are setting up a something related to business. Are you unifi Biz user?
