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: 

Apr 19 12:38:16 WARNING[9615]: chan_sip.c:1228 retrans_pkt: Maximum retries exceeded on transmission 68a2414694556e3ffbc4066f9fe6e109 at 10.1.1.190 for seqno 783509378 (Critical Response)
Apr 19 12:38:16 WARNING[9615]: chan_sip.c:1245 retrans_pkt: Hanging up call 68a2414694556e3ffbc4066f9fe6e109 at 10.1.1.190 - no reply to our critical packet.

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?
