Hi,

I am a bit of a voip newb, but it is the last leg of a project that we are working on.
Essentially what I am after is a hosted voip provider that provides the following

1. A static IP address
2. SIP enabled/forwarding (I think this is SIP trunking?)
3 delivers the DTMF tones as well

I am not sure what sort of product I am looking for (Voip / hosted pbx etc) or who provides it, I get a bit lost in the lingo.

Can someone point me in the right direction please and recommend a decent supplier.

Many Thanks!!
 
Hi

Most important thing that has been mentioned here is stay away from DSL ! In fact you requested a static IP so that excludes you from DSL anyway, Dont listen to the adverts , static IP's are not available on DSL. With regard to the SIP service i can assist you here and with some quality 'last mile connectivity with a Static IP . Feel free to PM me and ill gladly advise you on the options .

While I agree in part the comment about not running voice on ADSL (although it can be done exchange willing and with vibe in the mix - different discussion), static IPs have been available through a number of ISPs (IS, Vox, MWeb etc.) for a number years now on ADSL. Commonly sold as Business ADSL.
 
I think we have some misunderstanding here with regard to what a true static IP is . As pointed out above , 'So called' static IP's have been on offer for a while from various ISP's but as i said , 'dont listen to the adverts' The service that these ISP's provide normally use an L2TP IPsec tunnel ,so they pin an IP address on the end of the tunnel, ViBE does a similar thing to bypass the need for a static IP . So what we have here is a fixed IP , so if it fixed why is it not the same as a static IP ? the answer to this is in the tunnel protocol itself , when using VoIP, the UDP packets are very small and in this regard the overhead is high. VoIP in a VPN tunnel over DSL the overhead is massive, 50% or more higher than normal DSL
This is the downside of using this
 
Thanks for clearing that up.

I am aware of the technical workings behind 'fixed' IPs, but I haven't looked at overheads or efficiencies of voice over it. Interesting.

ADSL has massive overheads...PPPOE -> L2TP -> ATM
