[Freeswitch-dev] NAT issue with SBC

[Giacomo Vacca]

Hi Thanh,
my 2c to help you going through this:
- If asterisk keeps re-senging the 200 OK after an ACK was sent to it, you
should check whether the ACK was actually delivered, and if delivered
whether asterisk logged any error/warning about it. In general, you should
provide the SIP traces to get some help.
- You have a typo in your public.xml: 'asteirsk' instead of 'asterisk'. You
should check that.
(BTW I'm not sure this is a question for -dev, perhaps -users?)

Regards,
Giacomo
