[c-nsp] QoS for skype with nbar on 837 with 12.3(11)YZ2

[Giorgos Manousakis]

Dear All,

i am trying to apply QoS on my aDsl interface (2048/256) and i need to give
strict priority to voice traffic, including skype and g711.

I suppose that i can match the g711 by using nbar rtp audio protocol or by
using source ports that are know on my asterisk server.

Because of randomness of skype protocol that kind of handling does not
apply. 
I found that skype is included in nbar but only after 12.4 version. 
Unfortunately i cannot upgrade the ios of my 837 cause of lack of DRAM,
which is not upgradable. 
So i tried to find a pdlm addon for skype, but it is not available for stand
alone download (http://www.cisco.com/cgi-bin/tablebuild.pl/pdlm).

Can i found anywhere a skype.pdlm file? Is there any other way that i can
match this traffic? Could i try rtp audio for that one too?

Thanks
