Hi, cancel_branch (t_cancel.c) contains a segfault in lines 284-288 when cfg_get(tm, tm_cfg, reparse_invite) is true but t->uas.request is NULL. My suggested fix is below but I'm not 100% sure if this is really correct. cheers

What version of memcached/libmemcached is needed for the memcached module in master?

by Peter Dunkley

Hello, The memcached module cannot be built for "stock" Enterprise Linux 6 because the versions of libmemcached/memcached that come with EL6 are the wrong ones. Does anyone know what the right versions are, and is it worth updating the module documentation to specify them? That way if someone using RedHat or CentOS wants to use the memcached module at least they know what version to download and build. Regards, Peter -- Peter Dunkley Technical Director Crocodile RCS Ltd

Presence Proxy

by Jan Gaida

Hello I'd like to explain my scenario and the module I'd like to develop. I am hoping for comments whether there are already modules like that or which modules' API I could use to make the development easier. Scenario: I have two domains (A and B) with a Kamailio server in each of them configured as presence servers. The agents from both domains want to subscribe to few resources from domain A. Idea: In order to reduce traffic between the domains, the presence server from domain B shall handle the subscriptions internally and use an internal virtual presence-user-agent to subscribe to the resources in domain A. SIP Messages: Subscription: 1) Subscribe resource.domain.a, from each user agent ua_n.domain.b 2) 202 OK from kamailio.domain.b 3) If not already subscribed, Subscribe resource.domain.a from kamailio.domain.b with virtual user-agent 4) 202 OK from kamailio.domain.a (Repeat for each susbcriber) (Subscription has to be refreshed by an internal timer) Events: 1) Publish resouce.domain.a to kamailio.domain.a 2) 200 OK from kamailio.domain.a 3) Notify resource.domain.a to kamailio.domain.b 4) 200 OK from kamailio.domain.b 5) Notify resource.domain.a to each user agent ua_n.domain.b 6) 200 OK from each ua_n.domain.b (Internally, Kamailio of domain B has to forward the incoming Notify to all locally subscribed user-agents) I tried using the PUA module but it does not fit all my needs. Now I think I will have to develop my own module in order to achieve everything. Any ideas?

CentOS packaging and document for 4.1.0 - please help

by Peter Dunkley

Hello, I have been updating my .spec for CentOS 6 recently. I am trying to get as many modules as possible into the build without needing exotic dependencies. There is one packages that I can't include into CentOS at all (and it would have helped me if the documentation had been updated). There are two packages I think I can include (if people can help with a little work). This is all summarised at the end of the email. I'd appreciate any help people can give me. Regards, Peter *Modules I can't include - but need more documentation* - *app_mono*: simply won't compile with against the version of mono-devel in EPEL for CentOS 6. EPEL contains mono-devel 2.4.3.1 (which is presumably too old). The module documentation for app_mono doesn't specify a minimum version - it would be helpful if it did. *Modules I could include - but need a little work* - *app_java*: this compiles with small Makefile changes (as I discussed recently on-list). It'd be great if some Makefile guru could help-out and adjust this so that it can compile cleanly (and through an automated process) without needing to edit/patch the Makefile for each target system. - *memcached*: as discussed on-list between Henning and Charles, this should be relatively straight-forward to get working with a library version check. *Modules I can't/won't include* - *db_cassandra*: requires specific versions of thrift (and thrift is not available in the base or EPEL repos for CentOS 6 anyway) - *db_oracle*: requires the non-free instantclient-sdk - *osp*: requires the OSP Toolkit (not available in the base or EPEL repos for CentOS 6) - *jabber*: this module is obsolete - *iptrtpproxy*: I believe this module should be obsolete (and it certainly can't work with the standard kernel version in CentOS 6 anyway) -- Peter Dunkley Technical Director Crocodile RCS Ltd
