I had a disturbing problem with my G.729 licenses the other day and I'm hoping that someone can provide me with some insight since Google didn't. I have 2 Asterisk boxes, 1 acting as the main server with 10 G.729 licenses and 1 that is acting as a media gateway with 2 G.729 licenses. The gateway build is: CVS-02/16/04-23:57:06. I have a TDM400 card with 1 FXS board (unused) and 1 X100P card that is connecting a POTS line to the main server via an IAX2 connection. I should be using 1 G.729 license to connect the call to/from the POTS line to the main gateway. I had an extra license for the FXS board when I decide to start using it. This has worked fine for months but about a week ago, I noticed that all calls coming through this gateway were dropping when my Cisco phones were answering the calls. (The Cisco phones are configured for G.729.) It appears that the gateway didn't think that it had a G.729 license so when the Cisco phone registered to the main Asterisk server answered, the call failed. Here is the gateway log that I found to support this: Apr 25 17:55:33 NOTICE[2883600]: Got event 2 (Ring/Answered)... Apr 25 17:55:34 WARNING[131081]: No available g729b resources for channel 2 Apr 25 17:55:34 WARNING[131081]: Failed to build translator step from 8 to 6 There were no such errors on the main Asterisk server. The problem is that when the call that generated the above logs came in, there was no activity on the gateway or main asterisk server. (i.e. show channels returned 0 on both machines) Restarting Asterisk on the gateway box fixed the problem. Anyone seen license checkin/checkout problems on Asterisk? If so, what is the workaround other than restarting the PBX on a regular basis. Thanks in advance for any help.
