Hello all
im trying to install my first sip line but in vain.My customer gave me a static ip and a router with nat and firewall disabled so im using the lan2 interface and none for network topology.I dont use stun (anyway there is always a blocking firewall and i cant ping the stun server,normal?).Is it right that all the devices are connected in lan1 and internet in lan2?is there any interconnection between 2 interfaces or i should connect internet in lan1?
Right now the line seems to register from monitor but all my invite requests end up with bad request receive message and i can not see the digits i dialled in the from header...
Im pretty sure that im doing something reaally wrong so anyone who could help?
Thanx

if your LAN2 is behind Nat then you need to open Port 5060 to the LAN2 IP address. You do not necessarily need Stun on Startup, but do enter your public IP address and port 5060 is the network settings.
You should be able to ping the STUN server (are you pinging localling on your PC or using Ping in SSA)
LAN1 does not need internet access for SIP.
You need a default route 0.0.0.0/255.255.255.255 via your router on LAN2.

Once you have all this you can create your Trunk and valid URI, along with SC to dial out but you are better off checking the Help file for this.

Post your trace from Monitor (SIP, ERROR & Print only) for help.

i ping the stun server from my computer with no response.Right now i dont use the stun thing at all and the line is registered succesfully (i get rx ok when i send tx register)

are you sending 4N to ARS or direct to the URI Trunk?

If using ARS:
4N
N
ARS Table

ARS then should be:

N;
N"@sip1.voipbuster.com"
Trunk Number set in URI Tab of SIP Line

If not using ARS then use the short code in my earlier post.

You are not seeing digits because you are not sending them correctly via a valid short code method. Always post the monitor output with each post.
