Already in the voicemail.conf file, I added the extension 500 and kindly find below my voicemail configuration:
0 => 1234,Gama Operator,Operator@gama.com
500 => 1234,Operator,Operator@gama.com
501 => 1234,Employer Name,email@example.com
502 => 1234,Employer Name,firstname.lastname@example.org
Asterisk version is 1.8 and currently I am getting this warning message:
[May 7 19:32:46] WARNING: app_voicemail.c:5535 leave_voicemail: No entry in voicemail config file for ‘u500’
So what I might be missing?
