My internal lan is small, 100mb, all wired. aastra phones.

.......
142/...     10.10.10.42      D       A  5060     OK (136 ms)
144/...     10.10.10.44      D       A  5060     OK (138 ms)
145/...     10.10.10.45      D       A  5060     OK (133 ms)

But pings are < 1ms:

ping 10.10.10.42
........
rtt min/avg/max/mdev = 0.479/0.483/0.497/0.021 ms

Why are the sip latencies so high? And is it a problem? And if so, how 
do I fix it?

FWIW, latencies to outside providers over nat are close to ping:

jnctn/....                     5060     OK (7 ms)
teliax/...          N      5060     OK (7 ms)

ping <teliax ip address>
........
rtt min/avg/max/mdev = 3.471/4.120/4.466/0.288 ms
