the first call (even *600) after registration is not working?
Hi,
I have a stange problem - maybe s.o. can help? The first call after registration of the phone at voxalot fails allways. I hear everything but nothing I say is 'broadcasted'. Even if I call *600, the echo test: I hear everything, but nothing I say is repeated. I hang up and redial *600 fine, no problem! Same thing if I want to make an outbound call after registration - nobody hears me. If I call the second time - now it works? NAT is set to NO. voxalot's stun is entered. My WLAN-phone behind a WLAN-Router (dd-wrt). The phone's MAC is set to the max pass-through (QoS: Premium). The phone registers first at the router, hereafter at eu.voxalot.com: No problem. What can I do that even my first call after my phone's registration at eu.voxalot.com works correctly? Thanks in advance Carl

where is Voxalot's Router-Setup Howto?
Thanks Ron,
at your link I can read: Quote:
Due to the fact that this appeares even with the echo-test *600, it is s.th. between voxalot and me - fine, at least we can address the problem. So this raises some questions, that are essential but not answered anywhere @voxalot! 1) what are the rtp-ports (Voxalot uses)? Here I read that rtp uses:2) The sip-port Voxalot uses 5060 (and others?) Voxalot uses 5060 - can I use for the other 5061?3) what if my wlan-phone is not the only voip-device? What can I do if I like to do Voip (skype and other provider) via my pc (at least one second voip-device) as well, not only with my wlan-phone.Why is there nothing @voxalot that describes a clean setup of a router? I am sure that I am not the only person that experiences theses problems and Voxalot knows best what ports they are using. So where is the HowTo for the router/Firewall - all what I found by google ends with: call you administrator Greetings

Your ATA/Sip Phone/Soft Phone determines what RTP ports will get used. You would forward the RTP ports that it will use to that particular device.
AFAIK, SIP only uses a single port. The default is 5060, but you can also use 5061, 5062, etc. With multiple VoIP devices, you would have to set each device to a particular range of RTP ports and use multiple forwarding entries to route the appropriate ranges to the appropriate device. Skype doesn't use SIP/RTP and handles itself properly in most cases without any help. The relationship between SIP and RTP is extremely unclean at the protocol design level when it comes to routing behind and through NAT routers. This has nothing to do with Voxalot. Audio problems with VoIP where NAT routers are involved are a significant problem with all providers and aggregators. I wish I could point you to a one-size fits all cookbook set of entries to make in your router, but it simply doesn't exist. |

Hmm, Roon,
bad news. But due to this unsatifactory situation I'd like to suggest a second fast echo test. *600 explains everything needed to know for a first time use -ok! But in case you want to use it anytime you register it is pretty ennoying to wait until *600 has finished it explanation to ckeck the other audio-way by saying s.th.. So I suggest to establish a fast echo-test *666 (easy and fast to enter!) that just says "Voxalot's echo test" or "Voxalot's echo test. Now speak and listen" or s.th. like this? By the way - I once suggested this - it really could help to localize problems if voxalot's voice error messages would be like "Sorry Voxalot can't do this"! See, here in Vienna is one provider (#1) offering a access to e164.org (#2) to forward a call to voxalot (#3). Beside that I have two providers (#4,#5) and none all these 5 tell in case of an error, where this error appears. Bad service by all! At least Voxalot should start to be better by adding just Voxalot to all its error messages - no? Thanks, Carl

Don't know if this helps you,
but Brujula, a voip proider, has a echo test that starts, without intro, so maybe, by peering to their sipbroker code you can also do your tests ? |
