How to set substitution for symbol “+” in caller ID?
Since firmware version 188.8.131.52, Vigor V models support setting a substitution for symbol “+” in caller ID, that when receive a call of which number includes the symbol “+”, it can replace the symbol to a specific value. To set up the substitution, go to VoIP >> Phone Settings >>Phone1/Phone2 >> Advanced page, enable “Replace + digit in caller ID to” and enter a value. The value can be three digits at maximum, each digit can be a number from 0 to 9.
This can also be done from the command-line interface by typing “voip dsp cidplusedigit [enable:1/disable:0] [channel:0-1] [value]”. Where channel 0 is for FXS1(Phone1), and channel 1 is for FXS2(Phone2). By default, the substitution feature is disabled, and the value is “00”.
