HI, when using the phone function, the receiver hear my voice is distorted. I'm using cordless phone to make calls. The router will switch to 3G network when making calls.
When I tested using E5186S-22a router for calls function,using the same cordless phone no problem at all.
B618s-22d
Hardware version: WL1B610FM
Software version: 11.185.01.00.00
Web UI version: 21.100.26.00.03
Besides, the service provider has this VoLTE service but why this router can't support?
Kindly fix the problem asap.
Thank you
