Hello,

first I wanted to confirm there is still an issue with such case on maintained versions. Since 4.4, there were many changes to topoh module. You can test on your computer with Kamailio 5.2 and using sipp to simulate such SIP traffic. If still and issue, it will be fixed and you can backport to 4.4 locally on your system.

Cheers,
Daniel

Hi Daniel-Constantin

Thanks for your response.

Yes we are using Kamailio v4.4.x in production. In case we cant upgrade to 5.x right now would there an alternative work around for this?

Thanks again
Phillip

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


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

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
