[Asterisk-Users] Sending SABME continuosly. Urgent help needed!

[Steve Hanselman]

Hi David,
 
Sorry for the very late reply to this, but it looks as though you're in
PRI_NET rather than PRI_CPE, I believe that the network sends to a SABME and
you reply with an unnumbered response, Q921 is then established?
 
 
Regards
 
Steve

Hi, I'm trying to install an E1 PRI, and I need it working by
Monday, but although everything seems ok, I get no response to calls. 
        When I make a pri extense debug on span 1, I repeatedly get the
following:
        Sending Set Asynchronous Balanced Mode Extended
        [ 00 01 7f ]
        Unnumbered frame:
        SAPI: 00 C/R: 0 EA: 0
         TEI: 999          EA: 1
          M3: 3  P/F: 1 M2: 3 11: 3 [ SABME (set asynchronous balanced
mode extended]
        0 bytes of data.
        
        And nothing else.
        
        When making a call to that E1, I see the message "D-Channel on
span 1 up" 4 times, and then a Informational frame, with 
        TEI:000 EA:1 and anything else with zero (13 bytes of data).

        Then "D-Channel on span 1 downn", and finally, after a while:
        (...) Warning[11276]: chan_zap.c:5993 zt_pri_error: PRI: Read on

        I think I have Asterisk stable version 1.0, CVS updated today
        Can anyone help me? Please! :S

        The line has not CRC activated (I have asked)
        Thanks!
