iptel query

Hi, I am a regular user of iptel ser. I am facing an issue while trying to insert "P-hint" header field in 200 OK response to REGISTER message. I want to have a condition check. If condition is true, the P-hint header should contain a value and if it is false, it should contain some different value. Can any of you help me solve the problem?

Websocket transport and forward()
by Andreas Granig 01 Jul '13

01 Jul '13

Hi guys, Maybe I'm missing something, but when I have a stateless lb with websockets enabled, and I don't have mhomed set (meaning that I need to set $fs manually), how would I set $du and $fs correctly, if $ru is for example this: sip:bo87fffs@h7h3rerhg50k.invalid;transport=ws I tried all kinds of variants and now starting with the simplest approach possible, doing this for sending out the request to the websocket client: $du = $null; $fs = $null; forward(); What I get is this error message: Jun 27 12:30:53 spce lb[12104]: ERROR: <core> [action.c:437]: do_action(): ERROR: do action: forward: bad uri transport 5 Is there anything special I need to do? Does forward() maybe just not understand WS transport? I'm using kamailio 4.0.2. Any help is greatly appreciated! Andreas
