i have problem with incoming calls to Elastix.it can connect but there is only onway audio. the receiver cannot hear voice.
Its behind a mikrotik.
Also i used nat=yes to PeerDetails.
I think that there is a port blocked?
Ports from 10000 to 50000 are allowed. also 5060.
Any help...

Hi,One way audio its almost 100% of the time Nat problems, If behind a NAT, create an /etc/asterisk/sip_nat.conf file with AT LEAST these three lines: 1) nat=yes 2) externip=your.external.IPaddess (or externhost=your.external.hostname) 3) localnet=192.168.0.0/24 (assuming your network uses 192.168.0.x addresses). Then "asterisk -rx sip reload" at the CLI.

You have to redirect the ports udp 10000 to 20000 and the 5060 port try it that.
