1899 offer voice over IP (VoIP) calls

re: sipgate

In a normal conversation, the data volumes reach approximately 100 kbit/s

Interesting as I don't have Windows to run the 1899 software.

Standard ADSL = 512down, 256up which is not enough for the 100kbits quoted. 1mb cable from telewest is worse at 1mbit/128kbit.

Furthermore, you need bandwidth management to make the connection reliable. Easy in thoery but as I'm finding out this is very hard to actually get working.

Hmm. Not convinced. You only need bandwidth management if you're doing something else on the line at the same time. i.e. if you're about to make a call, stop downloading, close eMule, and quit bittorrent...

I've used various flavours of VoIP (Skype, SIP, IAX, Nortel MCS) on a NTL line (768k down, 256k I think up) for the last year with no issues. The only time I get problems is if I've forgotton to stop a download, or if Outlook decided to go drag down a big attachment.

I'm planning to build a linux router to provide BWM, as well as giving me an asterix server on the internet to connect to these services without NAT. I understand there is a Linksys WAP device you can load with custom linux firmware to do BWM as well, although I've not followed this up.

Wish I had gone for the linksys. Instead I chose the Asus WL500g because it has a printer and USB port. Unfortunately the WLAN port on it didn't seem to work, and access to it is out of bounds as far as I can see to the OS (it gets bunched with the other LAN ports as eth0 which then get bridged to eth2)

Good luck with your bandwidth endevours!

The 1899 software just doesn't work with my setup. However, I've got firefly calling out using 1899 and also got x-lite receiving calls through sipgate. I've also got firefly both making and receiving calls (I think). I can also get x-lite to make calls through 1899 and receive calls through sipgate, but when I make a call through 1899 I can hear the "0p per minute" message, and ringing, but nothing after that. The other end can hear me though. Is there a problem with x-lite? Does anyone know a fix?
Many thanks for the advice so far.

I can make outgoing calls on 1899 from my pc using Firefly IAX.1899.com but can't get sip to work - I get an error 408, no network. Could it be that my broadband router is blocking sip but not IAX. I have started to look at "port forwarding" on my Netgear router if that is the problem.

I am using Skype at the moment which works but would like to use the 1899 service of free calls to UK landlines including free connection.
I have downloaded the 1899 software but not yet installed it, anyone had experience of clashes.
I use a VOIP USB phone but used headset before getting the phone.

I'm using Firefly softfone with USB handset, configured for 1899 outbound and SIPGate inbound, with XP SP2. Works a treat.

:cool:

The newer version of the softphone window says "ready to make calls / ready to receive calls".
How can I receive calls on my pc when one of the registered numbers is my BT line ?
I am trying to work out how to receive calls to my sipgate "local" number that is also registered with 1899, but haven't succeeded yet with Firefly
Thanks

thanks, I'll check the settings in Firefly again - but do you think I need to open an ports on the router ? I have a Netgear 834G
