Hello Glenn,

you should try the latest 1.4 svn version. There was a part of code for
the subscribe handling, which tooks very long to be proceeded and in
this time no other sip paket (like the answer for options) is read.

this cause the high timerange you can see on qualify. the problem is
that asterisk was not able to handle this amount of subscribes just in
time. with my patch this problem should not exists anymore.

best regards

stefan

    i have never load tested this against 1.4 but with 1.6 i used 400
    subscribes per second 😉
