<P><FONT SIZE=2>Running asterisk 1.2.7 with latest zaptel on centos4.4. with Aastra 55i phones. Local outbound calling works fine, but ATT requires clients enter 7 digit code for long distance. All calls with 7 digit code are lost within 20 seconds of the call. This is the message I’m getting:<BR>

The strange thing is that when I use an xten softphone this issue does not occur. Is this a SIP signaling issue? Any help would be appreciated. This issue does not occurr with any other ip phone on our network. ONLY THE AASTRAs. any ideas?<BR>
