We are using 3cx v12 sp4. we have 8 yealink t38 g phones. We are starting to get really bad static when ever an extension intercom dials another extension and the called extension picks up on the speaker phone. If the called user picks up the handset and then goes back to the speaker phone the static is gone. Does anyone know what might be causing the static? It also seems to be random some times it happens and other times not. However I would say it is 75% of the time there is static.
Thank you
