Hi, Yes I’m interested in your patch; I’d like to be able to send multiple headers (Diversion in my case). For receiving there’s already a solution with the param parse-all-invite-headers=true. Best regards, Sjoerd.

There is a bug in freeswitch that makes it impossible to manage multiple headers with same name, either receiving or sending; the last value overwrites all the previous ones. I wrote a patch to correct it. I didn't get the chance to publish it yet, but if you are interested I can share it with you. Btw, I provide freeswitch consulting services for carriers. If you have any need, feel free to ping me.

In our case we have an incoming call with multiple diversion headers, we do some processing and want to add a diversion header ourselves to the outgoing call. What I’ve found so far is that for inbound calls one needs to set the profile param parse-all-invite-headers=true, this results in a sip_i_Diversion variable that uses the ARRAY:: syntax and has all the values I want. So far so good. Example: ARRAY::<sip:Carol@uas2.isp.com>;privacy=off;reason=unconditional;counter=2;screen=no|:<sip:Bert@uas2.isp.com>;privacy="full";reason=user-busy;counter=3;screen=no|:<sip:Bob@uas1.isp.com>;reason=do-not-disturb;counter=1 For the outbound call it’s more difficult, I cannot get FreeSwitch to produce multiple Diversion headers. The only syntax I’ve found is using comma’s in the value, like this: <action application="export" data="sip_h_Diversion=<sip:Carol@uas2.isp.com>;privacy=off;reason=unconditional;counter=2;screen=no,<sip:Bert@uas2.isp.com>;privacy="full";reason=user-busy;counter=3;screen=no,<sip:Bob@uas1.isp.com>;reason=do-not-disturb;counter=1,<sip:Bert@uas2.isp.com>;reason=user-busy"/> This results in a single diversion header with the contents I put in. From the RFC’s I understand that this is technically equivalent to 4 (in my case) Diversion headers, is this true? Is there a way I can convince FS to generate multiple separate diversion headers? Best regards, Sjoerd. BTW I’ve tested with FS 1.6.20 and 1.4.26
