hi folks. does any one have experience setting up E1 PRI in Shanghai, China? it works fine when we use SIP phone to dial out, however when using forward function on the same phone, it seems like it's dialing out but there's actually no respond from the phone company (China Telecom) and eventually the dial command will timed out. here's our PRI portion of zapata.conf: switchtype=euroisdn nsf=none pridialplan=unknown internationalprefix = 00 nationalprefix = 0 localprefix = privateprefix = unknownprefix signalling=pri_cpe hidecallerid=no usecallingpres=yes callerid=asreceived channel => 1-15 channel => 17-31 any clues? -- Edwin Lam <edwin@officegeneral.com> Systems Engineer, Office General, Inc.

As with all telcos, if things don't work properly asking China Telecom to help is usually a frustrating task. Steve
