You will find the following fields in Options (Figure 7.84):
Router with full DNAT?: If IPBrick is connected to a router, responsible for the access to the exterior (in terms of VoIP) and allowing the 'passage' of all traffic, it is necessary to select Yes and indicate the external address of that same router in Router public IP address;
IP address of the IPBrick public interface used by the VoIP service: IP address of the public interface of IPBrick responsible for the VoIP service;
Enable direct voice traffic: It allows to route the network traffic only in a interface and not in two interfaces, as usual;
Remove default national prefix (0): It removes national prefix normally used;
IPBrick Contacts Server IP address: The IPBrick Contacts IP address.
IPBrick Contacts Server DNS domain: The IPBrick Contacts DNS domain.
Get call source address from IPBrick Contacts: If activated, it goes to the Contacts' LDAP database and, if it finds the calling number, it will replace it by the name of the entity associated to that number (this option can also be used on internal calls).
Restrict Follow Me Addresses on MyIPBrick to IPBrick Contacts: By default NO;
Mask call source address on internal calls: By default NO;
Immediate answer on calls originated in a PBX: It is advisable to have this option enabled if you are using connections to SIP servers (ex: VoIPBuster, NetCall), in order to avoid timeouts in the PBX central. If, for example, you intend to define rates for the calls from the PBX, this option shall have to be deactivated to avoid that the user starts paying as soon as he dials the number.
Attendance Timeout: Time (seconds) during which the call is sent to the destiny phone, before being sent or routed to another phone;
Call Timeout: Time (seconds) during which the connection is trying to be established. If it expires, the attempt will be ended;
Timeout to hangup calls without sound;
Timeout to hangup calls on hold without sound;
Default register time: The time by which you request the operator a register (by default, 3600 seconds);
Maximum register time: The duration of your register (by default, 3600 seconds);
Number of register attempts: The number of times you attempt a register (by default, 0);
Enable SIP video support: Enables the support for SIP video. The signalling protocols doesn't support only voice but also video.
Attended transfer: If yes is chosen, you can define a key activation sequence to do a attended transfer. So you can stop using this feature from the SIP phone and use it from the VoIP server;
Blind transfer: If it's on yes you can define a key activation sequence to do a blind transfer. So you can stop using this feature from the SIP phone and use it from the VoIP server;
Call pickup: If it's on yes it will enable the call pickup. If a phone is ringing and the idea is to answer the call by using another phone, we can use the key activation sequence (*8 by default) plus the phone number to pickup the call. Example: *8111, will pickup a call from the phone 111 that is ringing;
Call pickup key activation sequence: Change here the default activation sequence (*8)
Group call pickup: With this option active, it's possible to pickup a
call from a ringing phone, member of the same group, by using the
defined key activation sequence (*7 by default), If the phone belongs to more than one call group, the last call to be ringing on any of those call groups will be the one to be picked up;
Global call pickup: If you choose yes it will enable the global call pickup. If a phone is ringing and the idea is to answer the call by using another phone, we can simply use the key activation sequence (*8 by default) to pickup the call. Example: *8, will pickup a call from a phone that is ringing. If we have two or more calls at the same time, will be picked always the last arrived call;
Global call pickup key activation sequence: Change here the default activation sequence (*8)
Phone lock: Permits to lock a internal phone, so it will be not able to make calls (it will still be able to receive them). To lock a phone you need to enter the key activation sequence and wait for a message. After that message you need to type the user PIN or PIN and password defined at IPBrick.GT - Users Management, depending of choosed user access validation. To unlock the phone the process is the same. If the option Allow phone unlocking by any valid user is set to NO, only the user that locked the phone or the defined Administrator unlock password will unlock the phone;
Do not disturb: If enabled the phone will be unable to receive calls. By default use *73 to activate DND on a phone, and *74 to deactivate;
Unconditional forwarding: Can be used to do unconditional call forwarning at a phone and by default uses key sequence *70. Example: Calls for phone 201 will be unconditional forwarded to phone 202. So we just need to do a *70202 at phone 201. To deactivate we type only *70;
Forward when busy: Can be used to forward a call when some phone is busy and by default uses key sequence *72. Example: If phone 201 is busy, calls will be forwarded to phone 202. So we just need to do a *72202 at phone 201. To deactivate we type only *72;
Forward when not answer: Can be used to forward a call when some phone do not answer and by default uses key sequence *71. Example: If phone 201 is not answering, calls will be forwarded to phone 202. So we just need to do a *71202 at phone 201. To deactivate we type only *71;
Retry Dial when busy: If someone is calling a number and that phone is busy, the caller will be notified and asked to activate the retry dial, if he decides to activate it, this option will run an availability check on that number. When it finally is available, the system will establish a connection between both numbers and both phones will ring. By default this option is Disabled. If you activate it these options will appear:
Retry Dial when busy key activation sequence: Change here the default activation sequence (5)
Timeout: The amount of time (in minutes, by default: 60) that the system will continue to run the availability check. When this period ends, the retry dial function will be stopped.
Restrict access to: Choose the addresses that may activate the retry dial function.
Call Supervision: If yes is active, it will only enable the call supervision feature. By default the key activation sequence is *9;
Call's prioritization: If enabled it will be possible to define priority levels for each route prefix defined in Routes Management. The level can be set from 1 (highest), to 10 (lowest). Example: In a LAN-PSTN route all the BRI lines are full. If a emergency call prefix (911) have maximum priority defined, when someone dials 911 some current call can be disconnected;

IP of server-signalling different from the media server: If a remote signalling service is running in one server, and the remote media server is running in a different one, this option must be activated;
Boss/secretary forward: This feature, when active, permits to more efficiently address the issue of call forwarding between boss and secretary, it assigns *79 as the key activation/deactivation sequence for the direct transfer between phones. You may alter it to another sequence if you so wish. By default this option is inactive.
