it can't hurt to ask. :)

hefty requirements ? i don't think so. actually, a lot of the requirements 
go together:

- deep core knowledge of IP stacks (freebsd-preferred)
- KAME's IPv6 stack

the above two are very much related, as the BSD IP stack is /the/ reference 
implementation for IP stacks, and KAME (which is the dominant IPv6 stack) 
is based on freebsd with that OS as the primary platform. it wouldn't be 
improbable for someone who knows the KAME stack to also know the freebsd 
stack, though the other way around may be harder to find.

in any case, if someone does know the freebsd stack, understanding the KAME 
stack is then a short jump away as it doesnt differ by much, with the 
exception of the packet header handling in the kernel.

- bonus points if your kungfu includes SCTP

and since the dominant SCTP implementation is in itself based on the KAME 
stack, this would be the logical next step for someone to pick up. i gave 
it bonus points because SCTP is not widely used outside of implementations 
of SS7 over IP networks, hence i wouldnt expect many people to have this 
kungfu.

given the three reqs above being met either fully or partly, it would 
follow (and it'd be a safe assumption) that the person concerned would also 
know C very well since all the above is written in pure K&R C. q.e.d. :)

- understanding of telecommunications architecture and protocols including
analog PSTN, E1 PRIs and SS7
- understanding of digital voice codecs (preferably G.711a, G.711u, G.729a,
GSM and iLBC)

these two, while a little divergent from the three reqs above, go together. 
anyone who understands digital/TDM based telecomms circuits will also 
understand the codecs used on them. once again, q.e.d. :)

since i'm working on bridging traditional TDM networks to IP networks, 
someone who understands both sides of the coin would be perfect. however, 
we /don't/ live in a perfect world, so i'd settle for two (or three) people 
who can combine to provide that same kungfu. in essence, i'm that bridge in 
the company today and i'm already at 150% utilization. i need someone to 
"share the joy". :)
