Hi guys, I installed Elastix 0.8.4 on my server, and my server connect to internet by a ADSL modem.. and I didn't use any firewall or router.
Calls between extensions on the LAN is all ok.
but when I'm making call to PSTN via the SIP trunk to my voip provider. I can hear from the pstn clearly ,but the pstn extension cannot hear anything from me..
Someone told me that maybe the RTP port was blocked, but I don't have any firewall or router enabled. the server connect to Internet just using a pppoe dialup link.
could someone tell me how to solve my problem ?thanks!
any help is appreciated!
