Re: [Openbts-discuss] Openbts-discuss Digest, Vol 90, Issue 16

[Varun K. <var...@ii...>]

Hi Thomas,
Thanks responding back.

I'm using UHD_003.010.git-90-g33419b5f, earlier when my phone got connected
to my openbts setup I reached till test tone call(2602), but was
unsuccessful in making echo call or call between two handsets.
I saw your discussion on asterisk, regarding problem with libsqlite3odbc.so
on 64-bit architecture. After rectifying the path of that file in
/etc/odbcinst.ini I was able to make call between two phones and somehow my
system also became stable. I restarted it more than 10 times and each time
it worked perfectly. Thanks for that file path :)

Right now, I'm looking for a way to manually edit subscriber registry
database without the use of nmcli.py. I tried editing
"/var/lib/asterisk/sqlite3dir/sqlite3.db" with sqlite browser, but failed
to do so. Let me know if you know something regarding this.


Thanks again for that file path though :)
