They asked me a couple of questions, Need To Test 10-Digit Dialed Number: Yes or No Need To Test Toll Free Dialed Number: Yes or No Need To Test Ringing With 180 Without SDP: Yes or No Need To Test Ringing With 180 With SDP: Yes or No Need To Test Ringing With 183 With SDP: Yes or No Need To Test No Ringing With 200 With SDP: Yes or No Want To Receive LNP Tags (ie NPDI): Yes or No Want To Receive SIP-T (ANSI/ISUP): Yes or No Able To Detect DTMF Digits: Yes or No Any idea on what to answer? Does SER support this options? Any clue is welcome. Pablo. __________________________________ Do you Yahoo!? Yahoo! Mail Address AutoComplete - You start.
