Regardless of whether or not it is the behavior you *want*, the behavior that {{chan_iax}} has is to use those two values for it's periodic qualifying of IAX peers.

The bug here isn't that we aren't using {{peer->maxms * 2}} - which is not the defined behavior - it is that we are not using the peer's {{qualifyfreqok}} value.

I'd be fine with a patch that changes the scheduling to {{qualifyfreqok}} - anything else would need the following:
* Another configuration option that instructs Asterisk to ignore {{qualifyfreqok}} and {{qualifyfreqnotok}} and instead use the last known qualify time, if available, as the time to reschedule the peer poke
* Such a patch would have to be written against trunk. It would be an improvement for {{chan_iax2}}, and as such is not a suitable candidate for inclusion in the existing release branches.

> When I try to use a qualify timer value for an IAX other than the default 2000ms, this value is not taken into account.
> I can reproduce this with this configuration:
> [remote-host]
> type=friend
> host=172.16.6.45
> username=remote-host
> secret=test
> notransfer=yes
> qualify=16000
> qualifyfreqnotok=30000
> disallow=all
> allow=alaw
> allow=ulaw
> allow=ilbc
> auth=md5
> encryption=no
> On remote host I configure a delay of 6000ms:
> ~# tc qdisc add dev eth0 root netem delay 6000ms
> The result in the logs:

> I believe this is due to a mixup in the chan_iax2.c code. When the peer is REACHABLE, the response appears to be expected within the default timer value*2. When it is UNREACHABLE, it uses the peer->pokefreqnotok value. IMO this timer value should be the same, whatever state it is, and the timer value should be peer->maxms.
> I did not test on asterisk 10 or 11, but by looking at the code it appears to be present in those releases as well
