[SR-Users] Re: Is there any way to modify the Refer-To header username?

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.

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! Regards, Shah Hussain
