Call Control Problem

Integrating the call control module on the opensips.cfg file makes opensips crash. The group is currently assessing the opensips configuration on what might be the problem. Previous configuration is being reviewed.

Update: July 13, 2009

After replacing the opensips.cfg file with an older configuration and re-intergrating the call control script of the opensips.cfg file call control is now working. The group is still comparing the two configuration files to determine why the newer configuration was not working. The group is checking on the possibility on the sequence of loading the modules (still in the process on determining what module).

Initial testing on the call control reveals that if the balance reaches below 4.00, the module will consider it low account balance hence, calls can not be made by the user. The group still exploring on how to set this into a much lower value.

Update: July 14, 2009 - 7:30 a.m.
The issue on why call control is not allowing calls if it reach certain amount is not related to any minimum balance which was considered by the group as a possibility. Further readings on the documentation regarding call control module call control has no minimum balance requirement. The group is still trying to determine on this is happening.

Update: July 14, 2009 - 9:30 a.m.
After reviewing the opensips.cfg configuration, the group has mistaken inserted the call control script before the session of the call has been fully established. After editing the opensips.cfg file call control was able to calculate the maximum time allowed for the call. Testing shows that call control was able to terminate the call when the is no longer enough for the call.

Another issue has been encountered however, when the call control module sends the BYE to both User Agent, the transaction is not properly accounted. Although the session is ended, radius is unable to update the accounting record for the call.
