Hi, If I do a "sip show channels" - I seem to be getting channels left open after calls have ended - any ideas why? I thought at first it was my Sipura SPA-3000 and that Asterisk was not detecting that i've hung up. However, after more testing, it seems to be just on Gossiptel calls - I tried a few of my other sip providers and the channels stay open after the call has ended but then dissapear after about 30 seconds. With Gossiptel calls - the channels just seem to stay open forever (or at least for a long time causing me to get errors about running out of rtp ports). I tried a software sip client and this has the same behaviour - channels left open for about 30 sec after sip calls but left open forever on gossiptel calls. Any ideas? Thanks! --ian
