I have spent days trying to solve my problem with sip and asterisk, Local users on the same network are ok but remote users behind various broadband routers can connect and dial but get no voice.
All people use eyebeam sip softphone.
Tried so many google guides Im now quite stuck.
- Asterisk 1.2.1 box with sip phones. rtp set to 10000-10500 udp
- Broadband Gateway server / Modem using linux NAT + iptables firewall
Forwads 5060 + 10000-10500 UDP from public IP to asterisk box.
4 . Internet
- Broadband Router Uses Nat (Remote user)
- Remote user lan with sip softphone.
(ASTERISK Box connects to normal bt phone lines via tmd400p (No probs witht this)
Local lan users on the same lan as asterisk all works ok.
Just the remote ones behind there own nat routers.
I cannot put the server in a dmz zone what alternatives are there.
Cannot really change to iax as the eyebeam softphone supports pc +mac+linux and Video and I have not seen a IAX softphone which supports all of this.
