Hi guys,
After a long time without using Opensips (almost a year) I tried to install
the opensips 1.10 and everything went well BUT when I make a call, there's
no audio, I know that is something because of NAT, but I have the nathelper
and rtpproxy configuration on my opensips.cfg.
There's anything else that I could take a look at?
Thanks
Atenciosamente.
