To #1: You need to add a "eat-the-rest" expression to your regex: "^sip:nobody@.*" g-)

Hi Elena,

I have a few questions in regards to avpops. Hope that you can help.

1. When avp_pushto() is used, the ruri is only used when t_relay is

called. However the uri match can't match the regular expression correctly. For example, I have this,

avp_write("sip:nobody@test.com", "s:default"); avp_pushto("$ruri", "s:default"); if (uri =~ "^sip:nobody@") { xlog("L_INFO", "got nobody\n"); } else { xlog("L_INFO", "didn't get nobody\n") }

It would say "didn't get nobody\n".

If I run t_relay, then it is sent to sip:nobody@test.com.

2. Is it possible to have a function to copy an avp to another avp?

The application is this, tm module uses one avp to define the invite timer. If there are multiple timer values defined for different scenarios, we need to copy the value into the one used in tm module. For example,

s:pstn_invite=100, s:sip_invite=20, If (the call is to pstn) { avp_copy("s:pstn_invite", "s:callee_fr_inv_timer"); } else { avp_copy("s:sip_invite", "s:callee_fr_inv_timer"); }

3. For performance reasons, we'd like to group all user preference in

one domain in one mysql table. Is it possible to specify the table name with an avp?

I run exactly the piece of script you sent and it worked as expected - I got " got nobody" :-) . To do some extra checking, you can put avp_print() before doing push - it will dump all current avps. Also, after avp_pushto(), insert a xdbg("ruri is %ru\n") to double check what's the RURI value.

for the moment no. I'm planning such a functionality along with the possibility of doing several operations on the avp value (concatenation/sum, replacing, etc).

No, you cannot load the table name from an avp. For more complex database operations please take a look to database scheme functionality : http://www.voice-system.ro/docs/avpops/ar01s05.html#db_scheme http://www.siphub.net/docs/avpops/ar01s06.html#avp_db_load
