[Users] Serial fork with AVPOPS - sr-users

1 Dec 2005

Hi,
I want to realize a serial fork. With the function avp_db_load() I load 
the addresses to forward the call and the function avp_pushto() rewrites 
the address. I have this problem (see the debug output):
I try to call 309(a)192.168.9.97
309 does not answer
Go to failure_route to write 400(a)192.168.9.97
The problem is that it comes executed another time avp_db_load(), and I 
don't understand why the voicemail is executed two times.
Thank's for all!
