We have CCM 4.2(3) located in the head office of my company and we have another branch for our company connected to the head office by MPLS line with bandwidth of 6Mbps.
All IP phones in head office and the branch registered on this CCM.
When i adjust Forward All feature on any IP phone in the head office, it works properly.
But, when i adjust Forward All feature on any IP phone in the branch, it gives fast busy tone and doesn't work.
If there any suggestion for this problem.
Thanks a lot for your cooperation.
If you are referring to Forced Authentication Codes (FAC) or CMCs enforced by CallManager then you will have to:
- Create a new partition
- Add the new partition to a new CSS
- Create a new route pattern to the PSTN without FAC/CMC, and put it in the new Partition
- Assign the new CSS to the lines in the CSS for CFA box
