 ==== epel repository ====
 If you want to use epel repositories to install Skype and other programs you have to exclude some packages in order to avoid conflicts.
-<code>[epel]
+<code># nano /etc/yum.repos.d/epel.repo
+[epel]
 ...
-exclude=libresample,fail2ban
+exclude=libresample,fail2ban,libsrtp,libsrtp-devel,nodejs,nodejs-devel,npm
 </code>
+==== Skype in/out calls ====
+  - Add [[https://fedoraproject.org/wiki/EPEL|epel]] and [[https://li.nux.ro/repos.html|nux.ro]] repositories, don't forget to exclude conflicting packages (see the section above)
+  - Install skype, java, x11 and dbus<code># yum install skype java xorg-x11-server-Xvfb x11vnc dbus-x11</code>
+  - Prepare logfile for SipToSis<code># mkdir /var/log/siptosip.log
+# chgrp asterisk /var/log/siptosip.log
+# chmod 660 /var/log/siptosip.log</code>
+  - Download and configure SipToSis<code># su - asterisk
+$ mkdir siptosis ; cd siptosis
+$ wget "http://latest-siptosis-package.tar.bz2"  # Look on Google for a website to download it
+$ tar xvjf latest-siptosis-package.tar.bz2
+$ nano siptosis.cfg
+     ...
+     #Sample AUTO config with NO registration
+     #  username and password not important in this mode
+     #  Set to available port to transport SIP messages on siptosis computer
+     host_port=5070
+     username=AsteriskUserForSiptosipTrunk
+     passwd=AsteriskPasswordForSiptosipTrunk
+     realm=asterisk # change this according to your PBX
+     do_register=no

+     #Examples:
+     *,sip:AsteriskUserForSiptosipTrunk@192.168.1.1:5060 # DON'T FORGET TO CHANGE USER, IP AND PORT ACCORDING TO YOUR ASTERISK CONF. For instance if you are using pjsip for extensions on port 5060 and sip for trunks on port 5061 YOU MUST use 5061 in this row otherwise SipToSis will try to authenticate itself calling the pjsip instance that doesn't know it as a trunk.
