Is there any way to strip a 3 digit access code off the Calling party number when the rest of number may vary?
i.e. YYYXXXXX where YYY is the site code and XXXXX is the extension number
Or YYYNNNNNNNNN again Y site code - N is a PSTN number..
I know it can be done easy with H323.. but is it possible in MGCP? I'm thinking not?
