[Serusers] avpops

Hi, Thanks for the great work on avpops. It is really an existing module which opens lots of opportunities. I read some document, just want to make sure I understood it correctly... . Every avp type should be saved in a different table. For example, I have two caller id settings for each subscriber, inter-domain and intra-domain. I should use one table for each setting. To load them, should I just use "avp_db_load" with their respective table name? Another question is, since the table name is optional, what happens if it is not given? When is it loading from? . It looks like that one avp can have multiple values. For example, you can have avp_write("sip:addr1@test.com", "i:2") and avp_write("sip:addr2@test.com", "i:2"). So avp name i:2 has both values. . If an avp has multiple values, I can use avp_pushto() to do a parallel forking. . Can I use an avp for the existing function? For example, I'd like to use different caller id inside "Remote-Party-ID". If I already load avp name i:10 with the right caller id, can I use append_hf() to add a new field with the avp? . In the example of Trusted IPs, what if I don't care about any username or domain? For example, I have a PSTN gateway shared by all domains. Should I put "" in uuid, username and domain columns? Then what do I put in source for avp_db_load()? It seems that source can only take either username or domain or both. Maybe define a uuid value and associate all gateways with the same uuid. Thanks again for the great work, Richard
