nikita Posted May 16, 2012 Report Share Posted May 16, 2012 Hi, We are trying to configure SNOM 300 to work on our network. After a configuration the phone successfully registered to a SIP server (which is located outside of our network) and can make outgoing calls. But the problem is that the phone is not receiving incoming calls. When I try to call this phone I get a fast busy. We forwarded a port 5061 on a router, but that didnt help. Here is the registration status of this phone on a sip server: Registered from: sip:0161100@82.166.238.165:49113;line=gld055d1 Last registered: 2012-05-16 10:49:52 Contact: sip:0161100@82.166.238.165:49113;line=gld055d1 Model: snom300/7.3.30 Please advise. Thanks. Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 16, 2012 Report Share Posted May 16, 2012 Sounds like a problem with NAT and the router configuration. Thats a classical. http://wiki.snomone.com/index.php?title=Server_Behind_NAT is a good starting point for that journey. Do NOT use STUN. It is one of the biggest misunderstandings in the SIP world that STUN is doing you any favor. Just use TLS (actually Plug and Play). Quote Link to comment Share on other sites More sharing options...
nikita Posted May 16, 2012 Author Report Share Posted May 16, 2012 So you are saying that we should trigger the port 5060 on the router and assign to this port(5060) incoming Ports range like 10000-10999?Should we also trigger some ports for RTP? Please correct me if I am wrong. "Just use TLS (actually Plug and Play)." - by saying this meant we should enable UPnP on a router? Btw we are using hosted PBX(if this helps) Thanks.

Btw we are using hosted PBX(if this helps) Oh so the PBX is running on public IP?! Then everything should be "automatic"... I would not mess with the setting on the router that the phone uses to talk to the Internet. If it does not work out of the box, you simple need to use a different router; but thats typically only in the case for < 30 USD routers or very expensive routers where you have to define a policy for each device. Plug and play might be the wrong description, but it is also possible to provision the phone from behind NAT. You should do that. http://wiki.snomone.com/index.php?title=Plug_and_Play is a good starting point. Quote Link to comment Share on other sites More sharing options...

The article that you provided, describes how to provision Snom using Snom ONE PBX(as I understood). The thing is, that we have just one snom phone in the office and we just want to configure it using the web interface. Is there a simplier solution to do so? Thanks.

Vodia PBX Posted May 16, 2012 Report Share Posted May 16, 2012 I believe it is easier to follow the PnP. Otherwise, you'll get easily stuck in outbound proxy, transport layer, buttons and so on and at the end of the day spend more time on the proper configuration than using the PnP.

nikita Posted May 16, 2012 Author Report Share Posted May 16, 2012 But to do this we need to buy additional hardware(Snom ONE), or no? Thanks. Quote Link to comment Share on other sites More sharing options...
pbx support Posted May 16, 2012 Report Share Posted May 16, 2012 Which hosted PBX are you using - snomONE or something else? Quote Link to comment Share on other sites More sharing options...
