Guys, hi. I have not solved the problem. Outgoing calls to remote extensions drops on 5-20 seconds. Incoming calls work perfectly. 

Hope you can help me. Attach updated logs: http://pastebin.com/HmKEDAUq


Thanks,

Try ulaw instead of g729, set directmedia=no

I see you are using FreePBX. I cannot help further.

I set canreinvite=very in the remote extension, and now the call not drops. Valid solution?

Hello. I have a problem with the configuration of a remote extensions. Calls are truncated at 20 seconds.

I got my my NAT firewall properly configured. Here I attached my debug in CLI: http://pastebin.com/gh34E69f


When the call is setup I see your Asterisk retransmitting the "SIP/2.0 200 OK" packet many times and getting no response. The other end needs to receive the packet and generate an "ACK". You need to trace where that packet is going and figure out why it is not reaching its target, or if it is, then why is the ACK not making it back. Thats your problem.


Thank you!

Thanks Steve. 

I think my problem is NAT. I'm using iptables, but I don't sure if I'm doing right steps.


In the principal router I've forwarded the ports, but in my firewall (iptables on PBX server) I'm not sure.  201.237.180.154 is my remote place.




#El NAT para el 5060 y el 10000-30000 (rtp)
iptables -t nat -A PREROUTING --dst 201.237.180.154 --proto udp --dport 5060 -j DNAT --to 192.168.1.180
iptables -t nat -A PREROUTING --dst 201.237.180.154 --proto udp --dport 10000:30000 -j DNAT --to 192.168.1.180
iptables -t nat -A PREROUTING --dst 201.237.180.158 --proto udp --dport 5060 -j DNAT --to 192.168.1.180
iptables -t nat -A PREROUTING --dst 201.237.180.158 --proto udp --dport 10000:30000 -j DNAT --to 192.168.1.180
iptables -t nat -A POSTROUTING --proto udp --src 192.168.1.180 -j MASQUERADE


iptables -t filter -A FORWARD --proto udp --dport 5060 -j ACCEPT
iptables -t filter -A FORWARD --proto udp --dport 10000:30000 -j ACCEPT





Can somebody help me to configure my NAT on iptables ? Maybe an example. Thank you again.

Guys, but ALL MY INCOMING CALLS (in remote extensions) WORKS FINE. Should be a NAT issue?
