we are experimenting a strange issue in our PBX.

By example: if we dial to the 100, the call is answered in 199. We dont have any redirection for that, but the cli show the same issue when request show peers. Aditionally, the user 100 use the ip address, and the cli show connected the user from (that ip is assigned to the user 199)

PBX*CLI> sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status Description
100/199 D Yes
Yes A 5060 OK (30 ms)

I check the sip 100 and (aparently) show all normal

PBX*CLI> sip show peer 100

  • Hi

    Check if the extensions 100 and 109 aren’t using the same username to register themselves.



  • hi.

    thanks for the recommendation. i discard that (and delete and create again the ext with random generated password), and the issue continue. El ene 21, 2016 10:59 AM, “Ethy H. Brito”

  • Sorry. I meant username/password you set on both terminals, not in asterisk’s ‘conf’ files.

    Also check if the IP addresses on the terminals are really those you wrote here and the ether addresses of both if they are on the same ethernet segment that asterisk is with arp -an | grep ‘192.168.11.\(100\|160\)’

    Can you “ping” them from asterisk?

    What are the outputs of sip show peer 100
    and sip show peer 109

    Note that your ‘sip show peers’ shows only one registered terminal. It means, in your case, that asterisk may be getting the same registration credentials from two different sources (IPs).
