Recently i have analogous (Internal server Error at sipxbridge with similar exeption in the log) problem. In my case the problem occurs (as far as i can localize it) when _sip._udp srv record points to different ip address then the a-record for the ITSP domain. So... just in case... i would check if dig -t srv _sip._udp.trunk.pstnconnect.nl and dig -t a trunk.pstnconnect.nl point to different ip addresses. If yes (different), then the problem is similar to mine. Rgds, Nikolay. _____

Has anybody seen this before? Any sugestions on how we can solve this, or workaround the issue? I am not a sip protocol expert, but what I see looks pretty normal to my eye. Except for the java error of course..... Thanks! Peter van der Salm
