    hi,

    i’ve migrated from issabel to vitalpbx recently, and currently i’m suffering one-way audio from external ip phones.

    vitalpbx version: 2.4.2-2
    ip phones: yealink t42s, t46s, t48s, t53w and t54w with pjsip extensions

    vitalpbx server is at a dmz subnet (192.168.28.0/24).
    local office ip phones use 192.168.6.0/24 subnet. i’ve been able to use endpoint manager to provision them. all these work good.

    i’ve tried a yealink t54w at other location. it registers and provision. local office users won’t get any audio from me if i call them, although i’m able to hear them.
    i’ve checked using the vpn module, it also registers, and i’m able to make calls, but the behaviour remains.

    i’m pretty sure i’m missing something… 

    i’ve attached screenshots for the pjsip profile i’m using, and the pjsip settings.

    i’ve tested using different external media and signal adresses (private ip, public ip, and public fqdn), with the same results.

    can you help me? thanks in advance.
