pretty annoying the AU server being down for almost a whole day and still is,. love Voxalot and all that but little support would be great for Voxalot's failover implementation system, so I wouldn't care if the AU server is down for a day or 2 as long as there is a backup server to use |

1. Set 'Proxy' and 'Outbound Proxy' to the desired Voxalot proxy such as au.voxalot.com. 2. When using DNS SRV one cannot specify any port number after the proxy used in 'Proxy' and 'Outbound Proxy', meaning do not write it this way: au.voxalot.com:5060. This excludes people accessing Voxalot on an alternate SIP port number. 3. A port number should be included with any SIP address used in the Dial Plan or Speed Dial Settings (example; echo@proxy01.sipphone.com:5060) 4. Set 'Use DNS SRV:' yes 5. Set 'DNS SRV Auto Prefix:' yes 6. For faster reaction to a failed proxy set 'Register Expires:' lower, 600 seconds may be the best choice here. After making these changes all Voxalot proxies will be available for use automatically. The order in which the proxies are preferred will vary depending on which proxy name you have entered in 'Proxy' and 'Outbound Proxy' (us.voxalot.com, eu.voxalot.com, or au.voxalot.com) and of course which proxies are on/off line. To keep audio latency at a minimum when using a distant proxy, make sure your ATA is sending your public IP address as the RTP contact address, so that voice packets will come directly to your ATA, not via Voxalot's proxy. To test for correct RTP contact address you should set 'Enable IP Dialing:'=yes then use one of your Speed Dial Settings to call *0@proxy01.sipphone.com:5060 where you will hear a message. If the message says "You are behind a SIP compatible router" that means your ATA sent the correct public IP address as the RTP contact address. On the other hand, if you hear something to the effect of "You may experience call completion problems behind this router" that means you must change some settings in your ATA, I have other posts about exactly what changes to make. |

I have no service either using Voxalot. I thought it was my router (Billion 7404VGP-M) but I can make outgoing calls bypassing Voxalot.

Thanks for your reply, im actually trying to fix my cousins ATA which he uses at his restaurant, wouldn't mind having this failover implementation working instead of bypassing Voxalot as he has relatives from overseas call him with Inum service,.
Anyway followed your instructions and his ATA has registered with Voxalot, though for some reason I can't call his Voxalot number, which should work if registered, only way I can test remotely,. I've played around with other setting below though it won't register,. So wondering about other settings like,.. Use DNS SRV:yes DNS SRV Auto Prefix: yes Proxy: au.voxalot.com Outbound Proxy: au.voxalot.com Register Expires:240 Proxy Fallback Intvl: 250 Register: YES Make Call Without Reg: YES Ans Call Without Reg: NO Use Outbound Proxy: GUESSING 'YES' Use OB Proxy In Dialog: GUESSING 'YES' Anyway think his is a sipura 2000 model |

"Register Expires:" would typically be 3600 seconds, but you might want it at 600 seconds in order to respond more quickly to a failed proxy. "Proxy Fallback Intvl:" 3600 "Ans Call Without Reg:" yes If your Linksys/Sipura SIP device is behind one or more NAT routers, set the following: (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 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).

Unfortunately your fine instructions are unsuitable for IP phones like my Siemens C470Ip.
Does anyone know of a workaround for these along these lines rather than just changing to another cluster - Bill |

Thank you again for teaching me how to set this up. Now we just have to hope that Voxalot improves the stability of their Australian servers. Regards, Ian. |

the links here about DNS whatever it is for failover is way over my head. I think especially since we are paying for this service that an automated failover to other servers on voxalots end would be very fair and reasonable to expect or at least request. |
