Connecting a Obi110 to a obi100 without Obitalk?

You can use the VOIP capabilities to connect them directly.  I am using an old Grandstream VOIP adapter as an extension phone and can also use it as an intercom.  I have both the Obi110 and the VOIP adapter set up so that if you dial 111 on either, it rings the other.


And how would one go about doing that?

M105,

Off topic.

Cool idea. Since you use the ATAs only as intercoms you might consider setting up the Grandstream ATA as a "Hot Line". Just lift the receiver and your OBi phone will ring right away. It would make a good door phone.


I am using the Grandstream ATA as an extension phone jack.  I can make and receive calls with it so I don't want the "hot line".  This is actually functioning over a wireless link to my back shop building using an old Linksys WAP54g as a wireless repeater.  Gives me Internet and a phone in the shop. 8)

I used this page as a starting point.

There are also a few threads on this forum about it that you can search for.

It's easy to connect two OBi's using SIP and without using the OBiTALK voice server.

The following additions to each PHONE Port DigitMap and OutboundCallRoute will cause the other unit to be called when 0 is dialed:


Physical Interfaces -> PHONE Port -> DigitMap : (...|0|...)

Physical Interfaces -> PHONE Port -> OutboundCallRoute : ...,{0:vg5(OBi)},...


Assuming each OBi is configured for SIP on SP2, add the following on both units:


Voice Services -> Gateways and Trunk Groups -> Voice Gateway5:

Name : OBi

AccessNumber : SP2(w.x.y.z:5061)

where w.x.y.z is the IP address of the other unit.


If SP2 is currently unused, you can configure it for SIP using:


Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1

Voice Services -> SP2 Service -> AuthUserName : (put anything here)

Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)

Voice Services -> SP2 Service -> X_ServProvProfile : B

Ronr: isnt there an assumption too that device 1 and 2 have 5061 port forwarded in their own  routers to the respective Obi devices for it to work.
also, can DDNS be used instead of Ip address?

in general:if one of the trunk in each device is configured with same SIP provider, then typically SIP2SIP is provided Free by the provider.
so, if you have callcentric configured on both devices, they can talk to each other for free.
even, if they are configured with different SIP providers, SIP2SIP is free as long as providers support free Sipbroker peering.

As i had mentioned in other posts, what i like about obitalk voice server is that since the protocol is not SIP, it works in countries where ISP  blocks SIP completely.
