SIP Via Header on 100 Trying

[Grant Bagdasarian]

Hi,

I came across a known issue, and am wondering about the progress of https://github.com/signalwire/freeswitch/issues/319.
One of our carriers is requiring the 2nd Via header to be sent back when Freeswitch triggers the 100 Trying.
I tried to disable auto-invite-100 and use the acknowledge_call application in the dialplan, but without success.

Is there a known workaround?

Regards,

Grant
