Konfigurácia podpory TLS v OpenIMSCore


OpenIMSCore poskytuje možnosť šifrovanej komunikácie prostredníctvom TLS. TLS sa aktivuje konfiguráciou P-CSCF. P-CSCF umožňuje šifrované spojenie (TLS) cez rozhranie Gm. P-CSCF musí poskytovať platný certifikát. TLS User Endpoint nemusí mať platný certifikát.  

Adding a new user to IMS platform using the HSS web GUI

To create a new user to existing IMS domain we will use web interface of the HSS. So navigate your browser to your HSS, in my case


 Creating IMS Subscription (IMSU)

Choose User identities from upper menu,


Testing IMS interdomain session

In our labs we have two IMS domains installed, one is OpenIMScore based, another is using Kamailio IMS components. We are trying to make interdomain sessions to test basic reachability. We provide call flows captured for interdomain call session establishment and the call flow established during sending of a file .

Building debian packages for OpenIMSCore

Based on guide from http://www.openimscore.org/debian_packages

Update source.list

Allows in sources.list non free packages to allow java installation

deb http://ftp.antik.sk/debian/ squeeze main non-free
deb-src http://ftp.antik.sk/debian/ squeeze main non-free

then install packages required for compilation (bison and libcurl4-dev have to be added compare to original guide)

Installing base OpenIMSCore platform on the debian squeeze - 32bit

This install guide is based on the official install guide from http://www.openimscore.org/installation_guide.

This guide describes the base component installation only. The platform is using four virtual machines, one for each IMS component (PCSCF, SCSCF, ICSCF, HSS).

Deployment OS is debian squeeze, 32 bit.
