How you make changes to your OBi config is a big subject. There are two methods, both have pros and cons. For now I suggest you stay with the Obihai preferred method, especially as your OBi may be remote from you:
Make changes via the OBi Expert Configuration pages. From your OBi Dashboard, click on your OBi number and follow the prompts to get there. To change a value uncheck both boxes to the right of the value and leave them unchecked. After changing the values on one page, press submit at the bottom of the page and wait a few minutes for the OBi to reboot. Then move on to the next page if required.
1. The above info and giqcass' advice should have cured this.
3. There are many ways to go! If you don't want to go with a paid account, then I suggest this for android:
Download the CSipSimple app to your cell phone (free).
Register for a sip2sip account (free). Install it on CSipSimple. I'll assume your sip2sip account id is
alalalal@sip2sip.info Now your cell phone can be called via your sip2sip account. Your OBi110 now needs a "fake" SIP account, I'll use sp2:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Service Providers -> ITSP Profile B -> SIP -> X_SpoofCallerID : checked
Service Providers > ITSP Profile B > General > DigitMap:
([^*]@@.'@'@@.)
Voice Services -> SP2 Service -> Enable : (checked)
Voice Services -> SP2 Service -> AuthUserName : Something (don't leave blank)
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
Voice Services -> SP2 Service -> X_UserAgentPort : 5061
Voice Services -> SP2 Service -> CallerIDName : Whatever
Voice Services -> SP2 Service -> MaxSessions : 4
Change the Line Port InboundCallRoute:
Physical Interfaces > LINE Port > InboundCallRoute:
{12345678901:sp2(alalalal@sip2sip.info)},{ph}
Now incoming calls to your OBi110 with CallerID 12345678901 should call your cell phone via your sip2sip account on CSipSimple.
There are other settings on CSipSimple to ensure it's "kept alive" etc, but we can do more detail if you choose to go this way and get this far! Sorry, it's quite a learning curve at the beginning. The good thing about CSipSimple is that it does integrate with the native android dial pad and will use your existing contacts.
4. Making an outgoing call from your cell phone via the OBi110:
OBiON app method: In your OBi Dashboard click on your softphone number – 290123456 – make sure that you have filled in the "OBi Voice Gateway" box with your OBi110 number – 200123456. Click save, wait for the OBi110 to reboot.
Now anything you dial from the OBiON app on your cell phone will be sent out from your OBi110 using its Primary Line. Default Primary Line for an OBi110 is PSTN Service, so calls will go out via the Line Port. This can be changed if required.
CSipSimple method: In your CSipSimple sip2sip account you need to tell it where your OBi110 is. Either your OBi110 is at a fixed IP address (your router's public ip address) followed by the OBi110's port (5061) so 123.12.112.10:5061 or you need a ddns address such as
alalalal.ddns.me.com:5061. Then you set up a filter rule for your sip2sip account on CSipSimple, which says "All – Suffix with @alalalal.ddns.me.com:5061.
Now when you dial from your native android dial pad it will ask you to choose between "mobile" or "sip2sip". Choose "sip2sip" and dial say 12345678901. This will be sent to the sip2sip servers as
12345678901@alalalal.ddns.me.com:5061 and your router will remove all but 12345678901 and send that number to port 5061, which is the OBi110 sp2. (Phew, nearly there!)
Change sp2 InboundCallRoute:
Voice Services > SP2 Service > X_InboundCallRoute:
{(alalalal)>(xx.):li}
Any call coming into sp2 with a CallerID of "alalalal" will be sent out of the Line Port to PSTN. This can be changed to include ringing the OBi110 Phone Port, or connect to the Auto Attendant etc.
There are some potential problems. For example sip2sip won't allow through numbers starting with "0". Many countries (including where I live) use "0" rather than "1" as a national prefix. This can be overcome, but you have enough to think about for now!
As said earlier, these are only two options – using OBiON or CSipSimple. Both are free, but obviously use your data plan. The OBiON app is a bit clunky and is in need of updating. CSipSimple is a learning curve all of its own, but can be very useful.
5. sip2sip does have a voicemail facility. I've not used it with my sip2sip accounts, so I cannot comment on it. I guess we should not expect too much from a free account!
I'm no expert on PBX etc. You may wish to post that separately after you get past all of the other issues in this post.
By now I expect you are banging your head on the nearest wall or have fallen asleep – don't despair – many of us have been through this and remained almost sane
