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.

Alternatively there is also the topoh module, which do not need any backend storage.

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. -- Thanks & Regards, *Ankit Jayswal* | Specialist - Software Development
