[Serusers] Dynamic Invite Timer w/AVPOPS

[Marian Dumitru]

Hi Paul,

The script looks ok. The problem is in other part; it took my some time 
to trace it - there is a bug in TM in setting the "fr_inv_timer_avp" 
parameter. Because of this, the AVP was not found and default value was 
applied for timeout.

Please find attach a patch to fix the problem.

Best regards,
Marian
