Hello, this is my first post on this forum and i have one question before i buy device.

Ok, so i have one project on my minde.
My ISP have free calls in my bundle of service for calls made to landline and mobile numbers so is it posible to use obi110 or 200 to configure this device so that i can make and recive calls on my android phone over internet and wifi so that i can have free calls on remote location from on my smartphone device but from landline number (similar device is voice bridge but i want to run service localy on my network and dont want to be tide to external servers)

so in summary i want disconnect my regural dect phone use regural rj11 splitter connect obi to one port on splitter dect to secund port on splitter connect obi to router and configure to use landline over network

Does the VoIP "line" that your ISP provides use SIP protocols?  If yes, do you have or can you obtain the details of the proxies and the registration credentials?

Some informations about ims (voip) can be extracted from vdsl2 router but not all some users have try to extract and use that info directly in sip apps but did no have success

Basicly router have rj11 port for connecting regural phone in to it and all configuration for voip service is configured using acs by my isp inside router

You can connect an OBi200 to your phone service using an OBiLine adapter.

1. On your local network you can register an Android directly to the OBi200 using a softphone and then route calls to your service.

2. Outside your local network you can use the following technique, but it requires another service (Sip2Sip).
This is the original thread:

Here is another version with fewer options:

3. Here are some direct connect options from outside your local network, but I don't know if they are reliable. I couldn't get them to work. Maybe ianobi will chime in.

See my version (reply#3) in the same thread. I did not test on a cell network.

It's interesting how this subject keeps coming up after five years or more. I have been using this direct ip calling method reliably using wifi and 4G for several years:

I keep an OBi110 running partly to carry out this function. I don't have an OBi2xx series to try it on. It definitely does not work on an OBi1032 IP Phone. The keep-alive STUN method does not seem to have been implemented even though the setting are there - that's a very low priority for Obihai firmware writers I would guess!

Warning: There are some variables with this setup, so YMMV. The main problem is likely to be routers seeing this unregistered voip traffic as unsolicited and blocking it. If this is a problem for you, then use one of the first two methods in azrobert's post which use SIP2SIP as a free registered service to connect your cell / mobile phone to your OBi.

What we are really talking about here is trying to find a work around for the fact that OBiON now works badly or not at all on most mobile platforms. The best answer for us OBi users would be for Obihai to provide a gateway to their servers using standard SIP protocol rather than their proprietary OBiTALK protocol. Then we could use any suitable softphone such as Zoiper and use our OBi log in details to access the Obihai servers as a gateway to our other OBi endpoints. This would mean Obihai could officially give up on OBiON and leave other companies the problem of continually updating their softphones.

Sometimes I think that Obihai just like setting us challenges  :)
