Look at the OBi110's call history for any errors or a reason for failure.
To access Call History:
Log directly into the OBi110 using the local interface.
Key the IP address of the OBi110 into a Web Browser.
Hit Enter
The UserID and default Password are both "admin".
Click Status on the left column.
Then click Call History.
Are you sure you defined the dummy SP2 trunk correctly?
It should look like this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer: 127.0.0.1
Voice Services -> SP2 Service -> AuthUserName: anything
Voice Services -> SP2 Service -> X_RegisterEnable: unchecked
Voice Services -> SP2 Service -> X_ServProvProfile: B
If SP1 is currently defined as an SIP service, you can use it:
{sp1(xxxxxx@sip2sip.info;ui=$1),pp(obxxxxxxxxx),ph}
QuoteI did a test with my other smartphone and setup a Getonsip account and be able to make sip calls on both each other than I presume this part is ok.
I'm not sure what this means.
Are you able to call the smartphone registered to Sip2Sip from a smartphone registered to GetOnSip?
