HI HO!

Correct me if I'm wrong, but it seems you trying to use the AVPops to capture a time stamp of the very first INVITE of a transaction? To get this same information, I've used the acc module.

For billing and user call logging purposes, I needed this info and have used: acc_db_request("CallStart", "acc"); in openser.cfg.

This logs a record to the acc table containing the sip_callid, timestamps, and in "sip_status" is the string "CallStart". I then had various scripts parse acc to the format I needed for the end user.

Hope this helps, jj

But the name of the header changes for each transaction/dialog?

Not sure if I understand the problem correctly. Does the name of the header change?

No, it does not change during the lifetime of the AVP. The name is set to the call-id and stays constant as long as the AVP exists. The problem is imho the content of pseudo-variables can not be used as the names of AVPs.

# AVP 101 with alias modparam("avpops","avp_aliases","myheaderavp=I:101");

avp_printf("$myheaderavp", "$hdr(call-id)-$Ts"); avp_pushto("$Myheader","$myheaderavp");

Hi,

Is there a way or workaround to generate AVPs with header values as AVP name? It seems to me that the current AVP concept defines the AVPs at OpenSER startup, so header-value-based names are not feasible.

What I need is the following: Store/retrieve a (key,value) pair where the key is the current message's call-id and the value some combination of header values and pseudo- variables.

e.g. use the ops avp_printf("$hdr(call-id)", "$hdr(call-id)-$Ts"); avp_pushto("$Myheader","$hdr(call-id)");

in order to append the following header to the SIP message: Myheader: 23459@10.0.0.1-4235627623

Any idea how to do this in OpenSER?

thanks in advance --Joachim
