Problem when I use a router
My configuration is:MODEM>>SIPURA SPA3102>>PC and this works perfect with the SipBroker alias. I work with NO-IP to set up a DNS address. DNS is updated by PC.
If I use the following configuration: MODEM>>LINKSYS WRT320N>>SIPURA SPA3102 then the bell rings but there is no voice coming through. In this case I work with DynDNS to set up a DNS address. DNS is updated by the router. If somebody can help. Thanks a lot. |

The problem you mentioned is likely caused by your SPA3102 sending it's local IP address and port as RTP connection information (found inside SIP headers). When this happens the remote SIP device often does not send any voice packets towards you, so you hear nothing. Ordinarily, RTP connection information should be given as an external WAN IP address and port number. The following settings may fix your problem. (under SIP tab) SIP_T1: 1 Handle_VIA_received: yes Handle_VIA_rport: yes Insert_VIA_received: yes Insert_VIA_rport: yes Substitute_VIA_Addr: yes Send_Resp_To_Src_Port: yes STUN_Enable: yes STUN_Test_Enable: yes STUN_Server: stun.voxalot.com:3478 (or any STUN server such as 'stun01.sipphone.com:3478' or 'stun.sipgate.net:10000') NAT_Keep_Alive_Intvl: 179 (if your phone does not always ring on incoming calls when using '179' try 119 or 59, use highest number that works) (under Line_1 and Line_2 (or PSTN_Line) tabs) NAT_Mapping_Enable: yes NAT_Keep_Alive_Enable: yes NAT_Keep_Alive_Msg: 0000 NAT_Keep_Alive_Dest: $PROXY Register Expires: 3600 ---------- Optional settings, steps 1 - 4: Sometimes its preferable to operate the ATA independently of a STUN server. The benefit is that phone service can continue no matter if the STUN server is working. See steps 1 to 4 below. 1. Forward the SIP ports and the RTP port range from the router to the ATA. 2. Set "STUN Enable:" no 3. Set "NAT Keep Alive Enable:" no 4. The ATA must learn it's public IP address, either through normal SIP registration, or place your public IP address in the 'EXT IP:' field). |
