Hello,

are you using Kamailio v4.4.x? If yes, can you try with a newer version to be sure we do not hunt an issue that was already fixed? At this moment 5.2.x and 5.1.x are maintained branches.

Cheers,
Daniel

Dear List

I have an issue with topoh module.

Specifically for in-dialog requests, if the encoded uri is altered i.e. initial encoded contact uri is

Contact: <sip:X.X.X.X;line=sr-huAWi7oPBYsF.cC0L2lWOUlPwbSWOUl6wURTw24W>

and UAS sends an in-dialog INVITE like this adding tgrp and user=phone:

INVITE sip:X.X.X.X;line=sr-huAWi7oPBYsF.cC0L2lWOUlPwbSWOUl6wURTw24W;tgrp=1069912311;user=phone

  

Kamailio cant seem to match/decode this and responds "404 Not Found"

I have also set:

modparam("topoh", "uri_prefix_checks", 0)

As specified here:

https://www.kamailio.org/docs/modules/4.4.x/modules/topoh.html#idp37582868

But still doesn't work. Is there a bug with this module?

# ====================================================

# ================ TOPOLOGY HIDING ===================

# ====================================================

modparam("topoh", "mask_key", "secret")

modparam("topoh", "mask_ip", "X.X.X.X")

modparam("topoh", "mask_callid", 0)

modparam("topoh", "uparam_name", "line")

modparam("topoh", "uparam_prefix", "sr-")

modparam("topoh", "vparam_name", "branch")

modparam("topoh", "vparam_prefix", "z9hG4bKsr-")

modparam("topoh", "uri_prefix_checks", 0)

Thanks in advance for your support

Phillip
