Apologies for a simple newbie question. Following examples in the first two FreeSWITCH books, have been able to set up a SIP gateway, register, and receive calls. However I can't make calls. The dialplan is being entered, but 'hangs' at switch_channel.c:1055 New Channel sofia/external/16475551212 a) The provider name is "babytel". b) The dial plan bridge is to data="sofia/gateway/babytel/$1" (as per the books) c) The provider xml file is in conf/sip_profiles/external (as per the books) d) sofia status Name: external::babytel Type: gateway State: REGED Why is the bridge channel called "sofia/external/...."? And not "sofia/babytel/..."? Why does sofia status show "external::<provider>" (the books just show the provider name)? Can anyone explain why the bridge to the gateway does not occur? Thank you, Ian.
