Hi, My carrier doesn't like the invites that come from two specific customers I have, who both use something called VoipSwitch. It returns from the carrier as a Bad Request. Below is the dialog - I'm not sharp enough to see what's wrong - anyone?

Hello, maybe it does not like the two Max-Forwards headers in forwarded invite. Received invite does not have one, so you probably do two times max forward processing in you config, one time with 5 and one time with 10. Cheers, Daniel On 2/12/10 1:46 PM, Anders wrote:

Hi Daniel, Thanks...I think that I maybe understand... - let's see: What you're saying is that the problem is the missing Max-Forwards in the initial INVITE that I receive, right? If this is the case, should I solve this by rewriting the INVITE and add a Max-Forwards, and if so, how would I go about this? Thanks a lot! //Anders On Fri, Feb 12, 2010 at 11:01 AM, Daniel-Constantin Mierla <miconda(a)gmail.com> wrote:

Hello, On 2/12/10 2:10 PM, Anders wrote:

...

you have an error in the script. The max forwards header is added twice. Search for mf_process_maxfwd_header in your config. The maxfwd processing is: - if the received message has one, work on it - if does not have, add on Not being in received, kamailio will add one. And seems the config is doing maxfwd processing twice, with two different values. Cheers, Daniel

Hi Daniel, A double treatment of Max-Forward was too much, and after changing this all is fine. Thanks a lot! //Anders On Fri, Feb 12, 2010 at 11:15 AM, Daniel-Constantin Mierla <miconda(a)gmail.com> wrote:
