[Serusers] scope & database operations for avp_write

[Ramin Nikaeen]

Valued Colleagues,

 

Can anyone tell me what is the scope of avp_write?!

 

Is it global / per-transaction / per-message?!

 

I would like to have something similar to it with global scope so that I
can 

set the string "callfwd" once by executing:

avp_write("sip:211 at 10.1.10.22:5060", "s:callfwd");

 

and then keep using it for each SIP message processing using:

avp_pushto("$ruri", "s:callfwd");

 

Also, do the avp_write and avp_pushto involve Database access
operations?!

i.e. Does avp_write store the string in database and avp_pushto looks it
up

form the database or is the information stored in memory?!

 

I want to avoid database access to ensure improved performance.

 

Thanks

 

ramin
