[SR-Users] "Help with dialog $dlg_var(cseq_diff)"

[Daniel-Constantin Mierla]

Hello,

$dlg_var(cseq_diff) is incremented after sending the invite out from
failure route, being done when forwarding callback in dialog detects
that the cseq value has to be incremented.

I am going to test and see if there is an issue -- uac_auth() should set
some internal flag to tell dialog to increment cseq.

Cheers,
Daniel
