Hello,

actually in this case is better to use first tobody.params and then param transformations:

  - https://www.kamailio.org/wiki/cookbooks/5.2.x/transformations#parameters_list_transformations

Hi Ionut,

if you are referring to URI parameters, there is a transformation for that :-)

Cheers,

Hello,

Thank you for your reply. One more question. How am I supposed to access parameters inside a header. If the header has this format

<URI>; reason=someReason;index=someIndex

Is there any othere way than using regex to access these parameters?

Thank you,

Ionut

Hello Ionut,

if you like to do it in the cfg - just some ideas:

- iterate in a loop over the number of headers $hdrc

- access with the loop variable the respective header $hdr[i]

- do your operation, save temporary results in another $avp

- finish the operation by appending your header from the $avp

These PVs are (as usual) documented in the cookbook.

Cheers,

Henning

Hello all,

I am trying to implement RFC 7544 in kamailio.cfg, more specifically to transform Diversion header into History-Info. To do this I need to iterate over all Diversion headers and be able to get all the parameters from it. At first I discovered $di core variable, but I can access only the first header with it. I discovered kamailio selectors but I can't index them with a variable. I came to the point where I want to implement variable indexing to selectors but after I saw this API is quite complex I thought to ask here if there's any other solution to do this?!

Thanks,

Ionut
