Strange problem with sip client connecting on the wan side



  • Hi all,

    I post this in the NAT section because i have a feeling this is a NAT issue.

    This is the setup: VDSL2 line –> Modem --> Wan --> PfSense --> Lan --> Freeswitch

    I have voip phones on the lan that work perfectly. I also have a sip client on my iPhone, and when connected to the Wifi network at home, it works perfect, however, when connected to the wifi at work or using 3G the call gets interrupted after about 30secs.

    Did anyone else encountered this before? What am I overlooking here?

    Thanks in advance,
    Eric
