### Description I have the following URI: ```INVITE sip:123456789;phone-context=+1@192.168.1.1;transport=udp;user=phone SIP/2.0``` I want to remove the phone-context parameter from the URI, so I've tried to use the function: ```uri_param_rm``` from the siputils package: ``` if (uri_param_rm("phone-context")) { t_relay_to_udp("192.168.1.2", "5060"); exit; } ``` But this doesn't change anything, this parameter is still present in the URI. I tried to use ```msg_apply_changes``` (just in case) function before relaying it - the result it the same, the parameter is still there. Also, I've noticed that this function is not working either: ``` if (uri_param_any("phone-context")) { xlog("L_INFO", "Phone Context"); } ``` while this one: ```get_uri_param("phone-context", "$var(phoneCtx)");``` - seems to be working fine. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.2 (x86_64/linux) e292ba ``` * **Operating System**: <!-- Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...; Kernel details (output of `lsb_release -a` and `uname -a`) --> ``` CentOS 7 X64 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3321 You are receiving this because you are subscribed to this thread.
