Re: [Serusers] avpops

Hi Richard, thanks for your review. Indeed, flexibility it was one of the most important criteria when we decided to implement this module. Please find my comments inline. Richard wrote: Dispersing the AVPs between multiple tables is not a must; you can place them all in the same table. But in the case you have a considerable number of AVPs, it should be better (from database access point of view) to split them (usually on type / functionality criteria) between several table. This is just a suggestion for a more efficient way of using the DB support (you gain some boost by reducing the query time by reducing the number of AVPs per table). So, to load AVPs from a specific table, use "avp_db_load" with the table name: avp_db_load("$ruri","i:123/db_table"); if the table is missing (is optional) the default table will be used - it's a module parameter. Yes, you can have more AVPs with the same NAME/ID and different values. In your example you will end with a list of two AVPs with same ID. IMPORTANT: note that the AVP core (in SER core) keeps the avp list in revert order (it does insert at the beginning), so last added avp will be the first to be used. yes, correct. But be sure you use the 'g' (global) flag. Without it, only the first AVP will be used. You can do parallel forking, by pushing whole RURIs or by pushing only usernames (the domain part will be the same as original in all branches) or by pushing only domains (the username part will be the same as original in all branches). To add an AVP as header you need to use also avp_pushto() like: avp_pushto("Remote-Party-ID/request","i:10"); this will push into the request the header: Remote-Party-ID: value_of_i10_avp Be sure you have the entire header body in the AVP. No - at least one of this db filed is required to be able to load an avp . For loading, the AVP source can be either username or domain or both or uuid. In your situation, there are two cases: A. if all PSTN GWs are shared 1. use a fixed "uuid" to load them; for the moment avp_db_load accepts for uuid only an avp alias containing the uuid. So do: define as "avp_aliases=gw_uuid=i:4" and do avp_write("some_uuid","$gw_uuid"); avp_db_load("$gw_uuid","....."); B. if you have some PSTN GWs shared and some per domain: 1. use "domain" as source and put the shared GWs for all domains. 2. use to AVP types - for shared and for per domain GW; use a double load, for shared and per domain avps - for shared ones, put in DB only the uuuid field and for per domain ones put only the domain: define as "avp_aliases=gw_uuid=i:4" and do avp_write("some_uuid","$gw_uuid"); # load shared GW to AVP i:10 avp_db_load("$gw_uuid","i:10"); #load per domain GW also to AVP i:10 avp_db_load("$ruri/domain","i:10"); So, you will have in AVPs i:10 both the shared and per domain GW. Hope this helps, Ramona
