SIP Business Business £35/month

[#1]

Hi,
I am a PN fan - we have about eight PN Broadband accounts (I work for a charity). I am about to embark on the world of SIP thinking, in the first instance, of upgrading our London Office to the "Business/Business" £35/month account (Presumanbly thats an 'upto' 800Kup/8Mdown MAX product?)
I suppose my questions are:
1/ How likely am I to get a faster upload speed in Central London (Currently on an old non-max PN Business product 256K/up 2M/down)
2/ Am I really likely to get 800k/up? - How could I improve the chances of getting 800k/up
2/ Will I be foolhardy if I go with PN because you use traffic shaping? - The people in Usenet Voip space seem to be suspicious of Traffic shaping when it comes to SIP?
They seem keener on other ISP's who (apparently?) don't use it.
Any thoughts much appreciated, especially from anyone who is already doing it!
(I am unlikely to have more than three concurrent SIP sessions)
Many thanks,
Stef

Yes it is.

How far are you from your local exchange?

If you can get a decent download speed then you'll probably get a pretty high upload too. Here's a speedtest I've just done:

And here are my (not so good) line stats. I'm 2.32km from my exchange as the crow flies.

	Statistics 	Downstream 	Upstream 	
	Line Rate 	5568 Kbps 	832 Kbps 	
	Noise Margin 	6.3 dB 	        9.0 dB 	
	Line Attenuation 44.0 dB 	26.0 dB 	
	Output Power 	19.5 dBm 	11.9 dBm

Not at all! SIP traffic has the highest priority across our network.

Don't know as we haven't chosen the office yet 
BUT I have just noted that I am 990m from my home exchange (And I ordered a MAX boost last week)...
Could be sweet...
