Hi Henning,

Thanks a lot for the suggestion, it helped me to fix my issue. I used the replace function and it worked perfectly for my use-case!

4.7. replace(re, txt) Replaces the first occurrence of re with txt. Meaning of the parameters is as follows:

* re - Regular expression. * txt - String.

This function can be used from REQUEST_ROUTE, ONREPLY_ROUTE, FAILURE_ROUTE, BRANCH_ROUTE. Example 1.7. replace usage

... replace("server", "Kamailio SIP Proxy"); ...

Hello,

there are other functions in textops module, e.g. subst(..) that can be used to do replacements.

Have a look to this module for more details and examples. The approach of deleting and adding it new works as well, of course.

Cheers,

Henning

Hello Experts,

I wanted to check, is there any way to modify the username part of the Refer-To header in Kamailio? For example, I am getting the following header:

REFER-TO: <sip:sip.abc.domain.com:5061;transport=tls; ..... ; .... ; ...sip:sip.abc.domain.com:5061;transport=tls;%20.....%20;%20....%20;%20...>

the username part is missing.

Can I add a username inside it? For example, change it to

REFER-TO: <sip:123@sip.abc.domain.com:5061;transport=tls; ..... ; .... ; ...sip:123@sip.abc.domain.com:5061;transport=tls;%20.....%20;%20....%20;%20...>

REFER-TO: <sip:test-kam@sip.abc.domain.com:5061;transport=tls; ..... ; .... ; ...sip:test-kam@sip.abc.domain.com:5061;transport=tls;%20.....%20;%20....%20;%20...>

I could not find any solution in the mailing list, the only way was to remove the header and then re-add it.

Thank you!
