Look up sipviewer on the wicki - it will be your friend - downloand and install on a computer.
Make sure you have Winscp on your computer as well. Make sure you have Putty. Go to /var/log/sipxpbx on the server and do a logrotate. Instructions on the wiki. Try a call, and then run merge-logs from putty in /var/log/sipxpbx This will create a merged.xml file - open it with sipviewer to see what your calls are doing. Name the ITSP, and how you have it setup - Like the name of the company - we need to see if it is one that others have used successfully. If not, we can recommend some to try to see if it is the system or ITSP that is at fault. Time is off - generally means it can't get to the NTP server you have defined. Makes me wonder what you have for a router? What type of phone are you using? Can you call phone to phone? Can you call VP or auto attendant - 100 or 101? Have you ran Diagnostics Configuration Test - what were the results? Have you downloaded Preflight and ran it from another machine on the network - what were the results? These are the types of things that will help people see just how bad things are, or how close you might be to having things working. Now, get going............

We resolved the issue for several weeks by replacing a switch and cabling. On Thursday they had some transfer issues and the date/time were wrong after we rebooted the SipXecs because it froze while we were in it look for the cause of poor quality which had just returned. We restored a recent backup to the SipXecs thinking that the config may have been corrupted during the system hang. Note prior to restoring the config, calls to/from outside worked, only the date/timer were wrong and internal transfers did not work. Since the restore they cannot send or receive calls to the outside. A packet capture on the SBC (InGate Siparator) and at the ITSP reveal the following error. "Traversal licenses limit has been reached. Please contact your reseller to upgrade with more SIP Traversal Licenses." Upon talking with support of the SBC and ITSP, they analyzed packet captures and noticed that if a call is placed...the ITSP sends us an invite, then we send an invite back to them and this happens multiple times over and over, for just one VOIP call. They say that something in the phone system is causing a loop and that during normal call the following should happen...The ITSP sends an invite>>we send a 100 trying>>a ringing 180 or 183 is sent>>a 200 OK is sent >> then an ACK is sent and normal call progresses. We are working on setting up SipXecs 4.4 on a virtual machine and restore the most resent backup. However just in case this doesn't work, what logs do we need to look at for the above issues and does anyone have any suggestions on this? This client has multiple companies working off this SIP Trunk and we really need it fixed by Monday. Any suggestion would be appreciated.
