    Hi All,

    My diagram

    INTERNET<-NAT->Firewall  – VitalPBX ( 10.x.x.x) -IPphone

    I use SIP trunk to my service provider , incoming/outgoing call working fine until today.

    I can’t call out and receive any call from our VOIP service provider. after debug VOIP service provider answer they only received voip data from my VItalPBX private IP ( 10.x.x.x) not from my Internet IP so they reject my voip data.

    i have checked NAT configuration in Firewall , everything seem working fine except voip.

    Could you please help me to resolve this issue.

    Thanks you so much.

    Did you define your Public and Private IP address on SIP Settings?

    Hi Mrivera,

    the service provider block our connect because VitalPBX use private IP when send packet to service provide.

    If you have static public IP address, it’s must be configured in SIP settings.
