Hi!
I am new in ser configuration. My configuration: I use Audiocodes Mediant
2000 for PSTN gateway, ser-0.8.14 installed on my redhat 9.0 box,
audiocodes and welltech FXS's as user agents. Now, I can call succesfully
sip-->sip, sip-->PSTN and PSTN-->sip. My problem is that I need to
restrict some calls for some users, international, national and local
(sip-->sip calls). Can anyone help me? Here is my ser.cfg file.
Thanks!
