Tony,
I dont think codec matters in the OP's case. Although i sure hope it does. codec issues is something that sipx excels in because of it being a proxy. Unfortunately this is not one of those. RFC war? nah ---

    Each redirect is a hop.

    Thank you both for your kind input. I'm very impressed at the
    promptness of replies on the list so far!

    I've created a new issue at
    http://track.sipfoundry.org/browse/XX-9954, however this is the
    first issue I have created so there could be problems with it.

    Apart from the "Too many hops" error message in the sipxproxy
    log, was there any other indication that the problem could be
    related to max-forwards? In the pcap file I can see the original
    invite from the ITSP contains a max-forwards value of 10 which
    i'm guessing also helped in diagnosing the problem.

    Do you know if there's a resource available describinig the flow
    of data between each SipXecs component? I'm looking at the
    merged.xml file in sipviewer and must say i'm quite confused.

    Thanks again for your help.

    Paul

        Max-Forwards strikes again.   Your ITSP is sending a
        Max-Forwards of 10 which is consumed by the hops required to
        eventually land the call to the IVR.   The reason why it does
        not show when not using aliases is because it takes a lesser
        amount of hop and does not consume the max forwards.   I have
        discussed this with the developers and we agreed that we can
        introduce a reset-max-forwards=value  parameter in the ITSP
        account setting.   This would allow calls coming from these
        ITSPs with very low max forwards  to be rewritten.


        Please create a tracker for this in jira and attach the logs
        oisted here.

            Hi all, this is my first post on the forums and I'm a
            little wet behind the ears - might have to be a bit
            patient with me Laughing

            I'm having an issue with calls made from the PSTN coming
            in through the Internode (Australian) ITSP trunk I have
            setup in sipxecs. When I forward calls to an extension
            via System -> Servers -> *server* -> Sip Trunking ->
            Incoming Calls Destination, calls forward to VM
            successfully. However when I apply my ITSP DID to any
            extension, the extension rings and a call can be
            established but when the call is forwarded to VM, it is
            dropped at the far end. VM forwarding also works as
            expected during internal calls.

            Attached are two sets of logs and traces: one with
            aliases configured and one with calls passed straight
            through to an extension.

            Thanks in advance for your help.

Paul
