    With UDP, SIP messages which exceed MTU size need to be fragmented by IP layer which can cause hard to diagnose issues with lost packets. All routers in between need to allow for fragmented packets which is not always the case. Especially in VPN environments. 3CX should support TCP signaling to the phones for this reason.
