[Openbts-discuss] Problems making calls or sending messages between phones

[SAMUEL W. <smw...@ya...>]

Hello Guys,I have built and configure OpenBTS 5.0 on an Ubuntu 14.04 LTS 32 bit OS. I am following instructions from the book Getting Started with OpenBTS by Michael Ledama. 

All the test communications with the base station are ok, such as: the phones can register on the BTS, the test tone call  and echo call are OK, I can send and received direct messages from the OpenBTSCLI correctly, and I can also send a message to 411 and I will receive a message showing the IMSI and the phone number that I registered with using the nmcli.py software.

However, when I make calls between the phones, it does not go through, and If I try sending a message it says the phone number is not registered. But I can see the registration details in the database.Please guys, any help will be greatly appreciated.
Ralph, can you please weight in on this.
ThanksSamuel
