Please check with your PSTN service provider (or traditional PBX specs) for which caller ID
scheme they/it support. If you are not sure about which to use please refer to Table 10 (FXO
Lines Test Tab Definition). This tool will run an automated test to determine the proper Caller ID
Scheme so the gateway can properly detect the Caller ID.
Similarly to the cases explained above we can specify a caller ID scheme for each channel
independently.
Default is "relay via From header". You may also select :
"relay via P_Asserted_Identity header"
"Disable" : Caller ID feature will be disabled.
"Send anonymous" : All calls forwarded to VOIP end will be sent as anonymous.

You can enable or disable ECM (Error Checking Mode)
