Absolute noob to Asterisk & PBX.
Followed steps here -http://www.freepbx.org/support/documentation/howtos/howto-resolving-audio-problems
Read this and implemented multiple times (Including Asterisk SIP Setup)
sip.conf has not been modified outside of the GUI. rtp.conf through modified through Linux CLI as instructed in 1.
Ports 5060 & 10000 - 20000 have been forwarded by the NAT Router to the PBX Server.
Extensions configured as explained in the wiki (two iPhones). 3CX Softphone configured on iPhone with the PBX Server through Dynamic DNS. RTP Ports on 3CX configured within the RTP Range. SIP Port set to 5060
- Get 3CX on iPhones to work as an extensions both remotely & locally with PBX Server.
- Install additional IP Phones & Softphones if the present situation works.
iPhones can call each other and converse without a problem when within local networks either physically or through VPN. When on remote networks, iPhones call each other, ring and answer calls, but no audio.
Have now hit a dead-end and can’t seem to figure out what is going on. Any help or guidance is appreciated.
