Hi, My configuration: Sipura 2000 Debian/Sarge Asterisk 1.0.1 built by msp@toshiba on a i686 running Linux I am calling 612@fwd.pulver.com which is Daytimephoneline of pulver.com and for the first second the connection seems to be ok and I hear: <thu .. rsda ..> and nothing more, which suppose to mean <Thursday, ...>. The echo line from 613@fwd.pulver.com does work the same. I never got an echo back, the connection seems to stay online. When I call somebody on pulver.com than it works. When I do a count <one, two, three, four, five, six,...> the person receives: <one, two, ..., ..., fi..e,...ten> . Same other way around. The connection will still be alive. Here my * output with (asterisk -vvvvvvvgc): -- Executing SetCallerID("SIP/2201-f8d6", "password") in new stack -- Executing SetCIDName("SIP/2201-f8d6", ""username"") in new stack -- Executing Dial("SIP/2201-f8d6", "SIP/612@fwd.pulver.com") in new stack -- Called 612@fwd.pulver.com -- SIP/fwd.pulver.com-29d8 is ringing -- SIP/fwd.pulver.com-29d8 answered SIP/2201-f8d6 -- Attempting native bridge of SIP/2201-f8d6 and SIP/fwd.pulver.com-29d8 == Spawn extension (home, 7612, 3) exited non-zero on 'SIP/2201-f8d6' my sip file starts of with: [general] bindaddr = 192.168.2.200 port = 5060 ; Port to bind to disallow= all ; Disallow all codecs allow = gsm allow = ilbc ;allow = ima-adpcm allow = ulaw allow = alaw externip = ipthatproviderhasgiventome localnet = 192.168.2.0/255.255.255.255 context = from-sip Is there any differense between 1st call and 2nd call? Could that be a bad QoS Problem? The Internetconnection is 256k/s and there is actually not much traffic on. Robert. -------------- next part -------------- A non-text attachment was scrubbed...
