The following fields in Options (Figure 7.66):
Router with full DNAT?: If IPBrick is connected to a router responsible for the access to the exterior (in terms of VoIP) that allows 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;
Intranet VoIP Server only?: 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;
Get call source address from IPBrick LDAP: If activated, it goes to the database LDAP of IPBrick defined in IPBrick IP address and in IPBrick DNS domain and, if it finds the calling number in the database, it will replace it by the name of the entity associated to that number.
Immediate answer on calls originated in a PBX: It is advisable to have this option connected 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;
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 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 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 yes it will enable the call pickup. If some phone is ringing and the idea is to answer the call 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;
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 yes it will enable the global call pickup. If some phone is ringing and the idea is to answer the call 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 some phone that is ringing. If we have two or more calls at the same time, will be picked always the last arrived call;
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;
Call Supervision: If yes it will only enable the call supervision feature. Be default the key activation sequence is *9;
Voicemail: Enables general voicemail for VoIP. The voicemail files will be sended allways by e-mail;
Call's prioritization: If enabled it will be possible to define priority levels for each route prefix defined in Routes Management. The level is 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 dial 911 some current call can be disconnected;
Enable advanced call statistics: If active will enable some fields at call statistics like: Total packets, codec, lag, lost packets, signalling and jitter. Note that CPU/memory load will be increased;
Store calls details records in csv file: All the call history in the default asterisk format will be saved to a file called Master.csv. This file can be downloaded acceding by ftp with username voipcdr and password L1opardo;
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 *79as 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.
