[OpenSIPS-Users] SIP session termination doesn't work properly

Mon May 18 17:56:33 CEST 2009

Hi Bogdan,

I just captured the two sessions with ngrep (attached to this mail). Suprisingly, the dialog between the two laptops is all good with ngrep.
But when I use the two mayah centauri hardware codecs, there is still the problem with the "404 - not here". Which brings me back to my assumption that it is not a opensips problem. Can you confirm that?

Thanks & best regards,
Simon
