[Serusers] SIP to AS communication => argument for investing in QoS

[Greger V. Teigre]

And then to QoS :-)

I'm not sure that I see the argument for investing in QoS either. I 
think the costs are higher than the willingness to pay ;-)  There seems 
to be some operators that believe there is a business case in it though. 
Maybe they extrapolate from the success of QoS sales in MPLS networks 
and assume that enterprises are willing to pay for QoS extended into the 
mobile data network?

>> I think it depends on where you come from ;-)  The underlying assumption is that an operator has made an investment where it wants some return. The big question from an operator's point of view is what is the best approach to get the return?  There will different answer depending on your market position and your feeling of strength. Operators are afraid of becoming just a bitpipe. It was the same issue for big network operators a few years back (and still is): become an efficient bitpipe (Level3) or a full communication services provider (AT&T).
