[Users] Adding headers to the CANCEL messages generated by openser

by Ardjan Zwartjes

Hello openser users, I'm trying to do something with openser but I haven't been able to figure out how to do this. So I hope somebody on the list knows the answer: In my configuration script I use append_hf to add application data to the SIP messages, this works great until the moment where I do a parallel branch. The invites work just fine since I can do the append_hf in the branch_route. The problem arises when one of the branches is answered, at this point OpenSER will generate CANCEL messages for the other branches and I have no clue on how to add header fields with information about the original invite to those messages. So my question is: Does somebody know how you can add headers with data to the CANCEL messages generated by SER in a parallel branch? Thanks in advance. Kind regards, Ardjan Zwartjes.

[Users] Diferences between "fix_contact" and "fix_nated_contact"

by Edson

Hi, Despite the fact that this two functions are declared on NATHelper and Mediaproxy modules, from a practice point of view, they appear to do the same, so when to apply one and another? Aren't there functionalities overlaped? Edson. ------ "It wouldn't be sell if it were easy..." (myself)

[Users] prefix in dispatcher

by Jayesh Nambiar

Hi, I am using dispatcher module in my openser 1.2. I am using ds_select_domain function in the script. What I wanted to know is, is there a way that I can prefix some digits to the ruri before sending to the selected domain. My scenario is: I have got two Gateway IPs in the dispatcher module. Each Gateway needs a different prefix before the ruri to process the calls properly. I am using the round robin algo in dispatcher. Now the question is how will I know what IP is being selected and how will I attach appropriate prefix? Is there a way to do the same in the dispatcher module. My configuration snippet: route[4] { #--Dispatcher route-- ds_select_domain("1", "4"); $avp(i:25) = 3; $avp(i:30) = $rd; route(1); exit; } thanks in advance. w/regards, Jayesh Send a FREE SMS to your friend's mobile from Yahoo!

[Users] avp_check() replacement? Openser 1.2?

by Brandon Armstead

Hello, I'm wondering if in OpenSER 1.2 if there is a replacement method to check if a value is inside an avp list, as follows: if($avp(some_avp_value) == "$avp(some_avp_list_value)/g"){ # do something } avp check equivlent: if(avp_check("$avp(some_avp_value)", "eq/$avp(some_avp_list_value)/g"){ # do something } Does anyone know if this is implemented or being planned for implementation, what are everyone else's thoughts on something like this? Thanks! -- Brandon Armstead

[Users] extraneous 408's

by Tim

Hello, Since upgrading to 1.2 we have begun to see lots of extraneous 408 messages. The CSEQ indicates they are associated with INVITE transactions. Weird thing is they happen well after the INVITE transaction is complete. Any ideas on how I can figure out what is going on here? These are generated by openser not proxied from another source. Tim
