[Freeswitch-users] mod_httapi issues

[Colin Morelli]

Anthony,

Just tried a number of test calls on master and am not seeing the issue
anymore. When I was going through the httapi source I saw that and thought
"this might be an issue" but for some reason I convinced myself that httapi
was using a different callback.

In any case, this must be some kind of absolute record-breaking response
time!

Thanks for the awesome response.

Best,
Colin
