Call Signaling
There are three choices for Call Signaling: H.323, SIP and SPP, the –SS models only support SIP and the –FX
models support SIP and SPP, but not H.323. It is best to select one of these as the protocol to be used, rather
than mixing them. Single Port Protocol (SPP) is a non-standard protocol created by Multi-Tech that allows
dynamic IP allocation. Generally, the default settings will work for most users and the individual parameters may
be changed if the need arises. Additional details for all settings are found in Chapter 4.
