Greetings Everyone…
I searrched the forum and got related topics but still in sticky situation…
My router has public IP and asterisk plus cdma gateway is running on a static ip the When a call comes from a voip to router -> asterisk -> cdma gateway -> the caller tone is heard on the softphone(outside local network)…but after 1 or 2 seconds of call pathcing the call hangs up and cli says to visit hte sip retransmittin url…well the voice is audiable on the sofphone for the 1-2sec…after which the call is cut…
my sip.conf settings
[general]
disallow=all
allow=alaw
allow=ulaw
allow=all
qualify=yes
port=5060
I am using asterisk 11.6.0
Any idea what I am missing…I did all the router nat settings…
You are transmitting the 200 OK with a private use contact address. That suggests that there is NAT in your network, but you have configured no way for Asterisk to discover its public address.
Greetings again…
jut in case if anyone is faacing problem of not registering sip phones from particual country…check for the sip port…in some countries the default 5060 …it is blocked
Well what I have gained from the above fact is "you should first collect all the port and protocol information for the area you are plannig to plant your solution …before buying any gateway or any other hardware else consider the alternatives if SIP port is blocked ".
Well there are ohter alternatives…if SIP port is blocked…
1.use proxy / try different port(instead of default 5060).
2.use VPN.
