by Patrick Wakano

Hello list, I was trying to yum install Kamailio 5.2.1 on a CentOS 7 from the http://download.opensuse.org/repositories/home:/kamailio:/v5.2.x-rpms/CentO… repo, but the kamailio-sipcapture-daemon-config can't be installed because it depends on the kamailio-sipcapture package, which can't be found...

Gracefully dropping all branches

by Andreas Granig

Hi all, I’ve a scenario where after lookup() I get multiple branches, and I want to drop some or all of them based on some filter criteria in a branch route before sending requests out. Problem is that if all branches are dropped, kamailio replies with some implicitly generated 500 server error since there are no more branches, but I want to send a 404 or 480 instead. Is there a way to determine if I’m processing the last active branch (so all others have been dropped already), so I can send a graceful reply like 404 or 480 instead of dropping this last branch as well if I decide I have to filter that one too? I’m thinking of a hash table table or something to track and decrease the number of branches for a call, and based on a flag (whether one of the previous branches has been sent out or all have been dropped so far) either drop the last branch or reply with an error. However I’m wondering if kamailio comes with a mechanism to determine the branch state out of the box? Thanks, Andreas

Topos and subst_hf

by Igor Olhovskiy

Hi! I'm using subst_hf to add some extra info to contact subst_hf("Contact", "/^(.*)sip:(.*)@(.*)$/\1sip:encei$var(extra_info)-\2@\3/i", "f"); With combination of topos it's giving me strange results like 2(26) WARNING: sanity [sanity.c:282]: check_ruri_scheme(): failed to parse request uri [sip:encei302e3734-btpsh-5c6c00ac-2e-f@172.28.0.74><sip:encei302e3734-btpsh-5c6c00ac-2e-f@172.28.0.74] Seems, it's doubling R-URI on in-dialog requests. If I'm disabling topos - all is ok. What is interesting - this can't be reproduced with remove_hf/append_hf mechanisms.

Problem with requests routing when topoh is enabled

by Leonid Fainshtein

Hi, I have Kamailio 5.1 and I'm using the topology hiding module (topoh) that is configured as the following: modparam("topoh", "mask_key", "...") modparam("topoh", "uparam_name", "....") modparam("topoh", "uri_prefix_checks", 0) Unfortunately Fanvil SIP phone modifies the remote party Contact's URI before it puts it as R-URI in the re-INVITE request. For example, The remote party Contact header: Contact: <sip:127.0.0.8;tr=sr-O2Sdn60d3qrt3otz3o7L.6pF.6mUr6lF3qpd> The re-INVITE request line: INVITE sip:127.0.0.8;tr=sr-O2Sdn60d3qrt3otz3o7L.6pF.6mUr6lF3qpd;user=phone SIP/2.0 As you can see, ";user=phone" was added. As result of that Kamailio tries to send the request to 127.0.0.8. If I disable sending 'user=phone' in Fanvil configuration then everything works well. I assumed that if uri_prefix_checks=0 then the topoh module should take rid of such URI modifications. Am I wrong? Is there any way to solve the problem except to modify the endpoint configuration? Best regards, Leonid Fainshtein
