[OpenSIPS-Users] strange issues with presence messages

[Alex G]

ok after more tests today it seems that subscribe messages are the problem.
Some of them are not showing ok responses from the phone they are trying to
subscribe for presence to.

is there any reason why some of these would get through and some not?
