Enabling local call identification

Introduction

As shown in
between the SIP server and Router B fails, the SIP server forwards the call back to Router A, which
then forwards the call through its FXO interface.
In this case, the call from Telephone A eventually uses two DSP resources. This can be avoided by
enabling the local call identification function, which helps to identify local calls. With this function
enabled in this case, the voice interface corresponding to Telephone A can be directly connected
with the FXO interface, thus saving the DSP resources.
NOTE:
• Whether or not DSP resources can be saved depends on the voice card.
• This function can identify local calls originated by SIP, and cannot identify local calls originated
by H.323.
