And this configuration does core-dump under certain circumstances. As you cant define the sip listen port for the proxy i cant really recommend meranetworks sip<>h323 proxy. Next sw we will test is the former siph323 open-source and now payware sip<>h323 proxy from sipquest. Ive the sipquest NDA allows me to post the testing results ill we post em here. Unluckily it seems like everyone in the SIP business wants a written NDA from you before they even tell you their fone number :) -- Arnd
