I have an Adtran 600 (12 x FXS, 12 x FXO) connected via Sangoma A101 to an Asterisk server which is in the lab for testing. The channel bank is disconnecting every few hours without apparent reason and no-one can tell why, not even Sangoma who have worked very hard to determine the cause of the problem. Any experience with this? I would like to load test the channel bank by hacing a script that places calls to all the ports in rotation, simulating the load of a busy office. Is there anything like that? Chris Mason NetConcepts Int: (305) 704-7249 Fax: (815)301-9759
