I have a problem with a customer: Freeswitch doesn't reply to all RE-INVITE (and all calls are dropped by customer switch after 180s for this reason). At RE-INVITE reception Freeswitch reply with a 100 Trying and never send a 200 OK. I have compared INVITE and RE-INVITE and to me seem to be ok, for example: INVITE: Call-ID: 26100859-3498991521-863759@SBC2.mydomain.com REINVITE: Call-ID: 26100859-3498991521-863759@SBC2.mydomain.com INVITE Via: SIP/2.0/UDP 192.168.1.4:5060 ;branch=z9hG4bK44ee87fffd4e657f4514fdad9de39f9e RE-INVITE Via: SIP/2.0/UDP 192.168.1.4:5060 ;branch=z9hG4bK0ed216868c20ca374c8893a4fb9a39b0 I have pastebin the captured packets: http://pastebin.freeswitch.org/14527 Can anyone help me?
