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 at 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,

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 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 at 45.118.162.x:5080;alias=10.52.26.102~5080~1>

NEW (Needed):
Contact: <sip:00912269240xxx at 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.
