Ordering the Hardware Echo Cancellation Option
Each separate Astribank or Xorcom IP-PBX** requires a single Echo Canceller card. The hardware echo canceller option includes 32 voice channels and support for up to a total of 144 channels. All ports/channels in the chassis need to be licensed for the module to function. Additional channels are licensed in bundles based on the telephony interface type:
Hardware Echo Cancellation Limitations and Configuration Tips
Before you configure a system that includes the Xorcom hardware-based echo cancellation (HWEC) module you should be aware of a few design limitations:
- HWEC is not supported in the C/XR1000 or CXS1000 models.
- For certain telephony module combinations, not all port types will be able to use the HWEC.
* Except for the low-end C/XR1000 and CXS1000 “Spark”, which do not support the hardware echo cancellation module.
** The echo cancellation hardware is an integral part of the Astribank devices with 6 or more PRI ports and does not need to be ordered separately.
