How to use two OBI110 as a Local Area Network Intercom
glfruta:
Can someone in this forum post a step-by-step procedure on how to program two OBI110 to act as a local area network intercom without using Obitalk since the local area network doesn't have internet access, just local intranet access.
Explanation of the configuration scenario:
I have a house where I want to connect two OBI110 to communicate two separate rooms. Both rooms have ethernet cables that are connected to the same router in the same subnet, but nothing connected to the WAN port (no internet). Since that router doesn't have internet connection, I cannot connect to the Obitalk servers.
What I woud like to know is if there is some way to set or configure the two OBI110's so I can call from room A to room B and viceverse by pressing a speed dial button to ring the other OBI110 phone or just lift the handset and have the other OBI110 ring the phone in the other room.
I just want to link the two OBI110 to act like an intercom and am not interested in placing phone calls to landlines nor call other phones.
I understand that in order to program the OBI110's I will need to temporarily connect the OBI110's to Obitalk servers to program them, for this I can do so by setting up a test network in my office that has internet access and properly program the OBI110's while connected to the internet. Once both OBI110's are programmed I can disconnect the internet in my office and test to see if both OBi110's can communicate without using Obitalk servers.
I would be very grateful if someone can explain me how to do it please.

First, get the IP address of both OBi's.
From a phone attached to the Phone port dial ***1
You don't need to use OBitalk to update the OBi110s.
Attach a computer to the same router.
Type the IP address of the OBi110 into your Browser and hit Enter.
You will be prompted for a UserId and Password.
Both are "admin".
On both OBi110s:
Setup a dummy SIP definition like this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Voice Services -> SP2 Service -> AuthUserName : (any userid)
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
To fix audio problem:
Service Providers -> ITSP Profile B -> SIP -> X_DiscoverPublicAddress: unchecked
On OBi110#1:
Define speed dial.
User Settings -> Speed Dials -> select any speed dial #, uncheck and set to:
sp2(anything@192.168.1.102:5061)
192.168.1.102 is IP address of OBi110#2
On OBi110#2:
Define speed dial.
User Settings -> Speed Dials -> select any speed dial #, uncheck and set to:
sp2(anything@192.168.1.101:5061)
192.168.1.101 is IP address of OBi110#1
Edit:
When you're finished updating a section, click "Submit" on the bottom of the screen.
When you're finished updating the OBi110, click Reboot on the top of the screen.

If you want to just pick up the phone and have it dial, search the admin guide for "hotline". I am not going to attempt a step-by-step procedure.

For Hotline
On both OBi110s:
Replace Physical Interfaces -> Phone port -> DigitMap:
(<S0:100>)
On OBi110#1:
Replace Physical Interfaces -> Phone port -> OutboundCallRoute:
{100:sp2(anything@192.168.1.102:5061)}
On OBi110#2:
Replace Physical Interfaces -> Phone port -> OutboundCallRoute:
{100:sp2(anything@192.168.1.101:5061)}
The above should call the other OBi110 immediately when the phone is taken off hook.
I tried it on my OBi110 and it took approx 15 seconds before dialing.
Edit:
It's probably a bad idea to replace the DigitMap and Outbound route. It's better to add the above rules.
The DigitMap should look like this: (<S0:100>|...........)
Add the route rules to the beginning of the OutboundCallRoute followed by a comma.
You also need everything in my 1st post except the speed dials.

I proceeded to set both OBI110's as described in your step by step instructions.
Tried calling from Phone A to Phone B and viceversa and they worked, but one thing I noticed is that every time I picked up the handset of the receiving phone I had to wait for around 6 seconds before being able to hear the calling phone. The same happens with the calling phone, for when I pick up the handset of the receving phone, the calling phone still has pulsating tone indicating as if the receving phone is still ringing. This tone remains for 6 seconds after I pick the receving handset until full voice communication between the two phones is established, which happens, as I mentioned before, after waiting 6 seconds with the handset in my hands on the receving phone.
Is there any other setting I need to program into the OBI110's so the voice communication is established immediately after I pick up the receving phone ?
