Hello Team,
I am in need to modify the contact header in Kamailio before sending an INVITE request to the SIP trunk provider. Basically the IP address I need to modify in the contact header. Please suggest a better way to do this. Below is an example.
*OLD (Existing):* Contact: sip:009169240xxx@*45.118.162.x:5080*;alias=10.52.26.102~5080~1
*NEW (Needed):* Contact: <sip:00912269240xxx@*10.52.26.98:5060 http://10.52.26.98:5060*>
I tried various functions from the textops module but no hope. I am looking for a function that can replace the contact header's value. Please help me with this.
Hello,
the topos module can do that, among other things. Alternatively there is also the topoh module, which do not need any backend storage.
Cheers,
Henning

Hello, Thanks for your reply, but I am looking to replace the value in the Contact header. Which function can help me to do this ? I tried, *assign_hf_value("Contact", "<sip:00912269240xxx@10.52.26.98:5060 http://sip:00912269240xxx@10.52.26.98:5060>");*
But that is not working properly, it assigns value but previous value also remains in it.

Hello,
Can you suggest directly replacing the value of the Contact header ? As remove_hf("Contact") does not work for me.
I need just *Contact: <sip:009122692405xx@10.52.26.98:5060 http://sip:009122692405xx@10.52.26.98:5060> *instead of, *Contact: sip:0091692405xx@45.118.162.x:5080;alias=10.52.26.102~5080~1*

Yes, When I use *remove_hf()* and *insert_hf()* it doesn't remove the value of the Contact header properly.
Below code executed: remove_hf("Contact"); insert_hf("Contact: sip:00912269240500@10.52.26.98:5060\r\n", "Contact");
I have given the sngrep INVITE request below after applying the above code. See the highlighted contact header not removing previous value properly.

it looks like you are handling contact manually but also call "fix_nated_contact/add_contact_alias" function as well. You can't call 2 functions for the same header - it breaks the logic of how kamailio deals with the config at the postprocessing. There are 2 ways to fix it: - remove nat helper functions touching contact ( preferred as you don't need it anymore for the INVITE flow ) - use msg_apply_changes after the first function (which I would not recommend as it rereads the message again and defacto Kamailio parses the same message twice )
However as Alex Balashow mentioned - this is a really bad approach - to rewrite contact on the proxy, and it has to be used for corner cases and you are not at one of them. You have to deal with Record-Route/Route headers to be able to manage the routing.

Hello, Thanks for your reply, but I am looking to replace the value in the
Contact header. Which function can help me to do this ?
I tried, assign_hf_value("Contact", "sip:00912269240xxx@10.52.26.98:5060");
But that is not working properly, it assigns value but previous value
also remains in it.

please do not add the Contact header as second parameter to the insert_hf.
Try this out:

Hello,
This way the contact header is *not* getting inserted.
Below syntax is only able to insert it. insert_hf("Contact: sip:00912269240500@10.52.26.98:5060\r\n", "Contact");
My problem is with *remove_hf(); *function only. It does not remove the value.

Hello, Yes, actually my call flow for outbound calls is, Kamailio => Asterisk => Kamailio (route(PSTN)). SIP trunk is available at Kamailio server. So, when final outbound INVITE goes to the SIP trunk provider it expects a particular Contact header IP, instead of Asterisk server IP.
