Forward
To make a call between a panel and an indoor video entry phone (monitor) by pressing the button of the required apartment or entering its number, the panel and the monitor must have the same building and unit number in apartment settings. Also for monitors, you must indicate corresponding information about the floor, apartment, and device number.
If there is no monitor, it is turned off or such settings are missing, you must make forward queues for apartments to redirect calls to IP addresses or SIP numbers.
For digital two-wire systems, it is obligatory to configure a forwarding queue for each apartment.
Second SIP Account
BAS-IP panels support two independent SIP accounts. The second SIP account can be enabled in addition to the primary one to provide parallel calling, alternative routing, or redundancy. Both SIP accounts have separate registration parameters and their own call logic.
The panel can use the second SIP account simultaneously with the first one or switch between them depending on the selected configuration.
Use Cases for the Second SIP Account
❶ Parallel calls to two different systems
The panel can send the outgoing call to two SIP servers simultaneously.
Examples:
• SIP 1 → BAS-IP Link;
• SIP 2 → local SIP PBX or VoIP provider.
This ensures that all devices registered on either platform can receive the call.
❷ Separate routing for mobile SIP apps or softphones
SIP 1 may be used for indoor monitors, while SIP 2 can be dedicated to mobile SIP clients or third-party softphones.
❸ Integration with external services
The second SIP account may be used for:
• guard/security centers;
• concierge software;
• call recording systems;
• VoIP service platforms that require SIP signaling.
❹ Migration or coexistence during infrastructure transition
When moving to a new SIP platform, the panel can keep:
• SIP 1 → current system;
• SIP 2 → new system.
This avoids service interruption during the migration period.
Both SIP accounts operate independently and in parallel;
These panels do not support assigning different physical buttons to different SIP accounts (because the models are buttonless);
SIP failover is not supported — if SIP 1 is unavailable, the call does not automatically switch to SIP 2;
The second SIP account is intended only for parallel calling or for splitting destinations between different systems.
During a call, the entrance panel checks its forwarding queue only when it fails to find any monitors according to the entered values of the building, unit, floor, and apartment. If you want to enable the Forwarding from the beginning (without searching the corresponding monitor via the internal protocol), you need to set different logical addresses for the panel and the monitor. For a detailed explanation of the correct logical address configuration, please refer to the Forwarding from the entrance panel article.
Forward settings
Two forwarding modes are available:
all at once: the call is made to all numbers simultaneously.
one by one: the call is made to the numbers in turn with a 20-second delay.
If you have an analog and IP device in the same queue, the All at once mode do not work.
How to make a new forward queue
Log in to the entrance panel web interface using the admin username and the password you created when first setting up the device or after a factory reset.
Open the Forward tab and click New Forward.
Enter your Apartment Number which consists of the floor and room number. For example, 223 indicates apartment 23 located on the 2nd floor. Entering this number on the panel the queue will work.
Enter the Forward Number (directions for call forwarding). You can add up to 8 numbers for forwarding. Calls can be made both via P2P and via the SIP protocol.
Format for calls via P2P:
Two formats for numbers are available:
sip:1@192.168.1.65, where 1 is the desired number to be displayed for the callee, 192.168.1.65 is the IP address of the callee SIP client (if you use a softphone, the IP address of a device where the softphone is installed);
sip:192.168.1.65, where 192.168.1.65 is the IP address of the callee SIP client (if you use a softphone, the IP address of a device where the softphone is installed).
Format for calls to SP-02 is:
sip:192.168.1.99, where 192.168.1.99 is the IP address of the callee handset.
Format for calls via SIP:
sip:5588@us.sip.bas-ip.com, where 5588 is the callee SIP number, and us.sip.bas-ip.com is the address of the SIP server, which can be either the IP address or domain name.
You can also use the short form and enter only the callee SIP number of the called device ("sip:" at the beginning and the SIP server address can be skipped). So, it is enough to enter 5588.
For the forwarding correct function, the SIP numbers in one queue must be registered on the same SIP server. For example, forwarding will work for your SIP numbers registered on the us.sip.bas-ip.com server.
Format for calling the handset of a digital two-wire system:
laskomex:2, where 2 is an apartment number.
5. Save the forward queue by clicking Confirm.
Forwarding will work correctly even if numbers for both P2P and SIP calls are entered in the same queue.
Example of panel operation in combination with a digital two-wire system
We are required to call apartment 27. When entering the 27 value on the panel, it makes a call via internal protocol to the monitor in apartment 27. If there are no answers from the monitor, the panel refers to the forwarding table to check if there are any records for apartment 27.
Then there are several ways for the panel to act:
if there is no record for apartment 27 or it is empty, the panel will end the call;
if there is a laskomex:27 number, the panel will call the Laskomex handset with the No. 27;
if for the 27th apartment the SIP or P2P number is entered, e.g., sip:1346@us.sip.bas-ip.com, the panel will make a call to the specified number via SIP or P2P;
if there are several numbers indicated, e.g., laskomex:25;sip:1346@us.sip.bas-ip.com, the panel will make a call first to the Laskomex handset with the 27th number, and then to the specified SIP number;
