Type of Service (ToS)

QoS in hexadecimal format. This is a part of the IP header that defines
the type of routing service to tag outgoing signalling packets originated
from the phone. It informs routers that this packet must receive a specific
QoS.
The default value is 0x60.
Values can be set in decimal (e.g. 96) or hexadecimal (e.g. 0x60).
