configure as "cas"; If span type is E1, the signaling configure as PRI or
SS7, then framing m
ust configure as "ccs"; If span type is T1, and the
signaling configure as PRI or SS7, then framing can configure as "esf" or
"d4"; If span type is J1, and the signaling configure as PRI or SS7, then
framing can configure as "esf" or "d4".

Advanced Settings
MF Back Timeout (ms)
MFC/R2 value in milliseconds for MF timeout. Values smaller than 500ms
are not recommended. -1 represents default value.
Metering Pulse Timeout (ms)
MFC/R2 value in milliseconds for the metering pulse timeout. Metering
pulse is sent by some telcos for some R2 variants during a call
presumably for billing purposes to indicate costs. Should not last more
than 500ms, -1 represents default value, and for A
rgentina the default
value is 400ms, for others is 0ms.
Allow Collect Calls
Brazil has a special calling party category for collect calls (llamadas por
cobrar) instead of using the operator (as in Mexico). The R2 spec in Brazil
says a special GB tone should be used to reject collect calls.
By default, this is disabled, which means collect calls will be blocked.
Double Answer
Some gateways require a double-answer process to block collect calls. If
users have problem blocking collect calls using Group B signals, please
try enabling this option.
Accept On Offer
By default, it’s enabled. In most of cases, this option should be enabled.
Skip Category
If enabled, the callee side will request the caller to send caller category
before sending caller number.
Note: "Get ANI First" and "Skip Category" cannot be enabled at the same
time.
Charge Calls
Whether or not report to the other end "accept call with charge"
. This
setting has no effect with most telecos. D
efault setting is enabled
