Generally the AS55X is connected (via LAN) to a PBX. In this case the SIP “peer“ mode
is the best choice. The AS55X is directly linked to the PBX. It only accepts calls from
peer IP address and it routes all call-setups from GSM to the peer IP address.
Optional the PBX can register to the AS55X.
You can configure two peers, but the AS55X will always proceed to contact the first
peer. If this is not reachable the AS55X will contact the second peer. Incoming call are
processed by both peers.
Notice: It is recommended that the AS55X operate with fixed IP addresses
and not with DHCP assigned IP addresses.

Amount of dialled digits from SIP to be ignored
Some PBXs sent the dialled number with a prefix to the wired network. The amount
of prefix digits can be ignored by AS55X to ensure a correct routing.
The amount of digits to be ignored, can be selected here.
Default value: 0

Prefix for suffix dialling to GSM
Some PBXs sent the dialled number without a leading zero or with another incorrect
string. To correct the prefix you can fill in a suffix that is assigned to the GSM
network.
Default value: not reported

Amount of CLIP digits from SIP be ignored
If you use the callback function of the AS55X, you can make an adjustment of the
CLIP here. When the PBX sends more CLIP digits of a call than needed for a callback,
you can set the amount of digits that have to be ignored.
You can verify the correct function in the “call setup list” in services menu (see 7.5).
Default value: 0

Prefix for CLIP from SIP
If you use the callback function of the AS55X, an adjustment of the CLIP might be
necessary. When you need some additional digits for a correct routing, you can fill in
up to 21 digits in front of the saved number.
