MCU Media Server

Всем привет.
По работе появилась необходимость сделать программный сервер многоточечных видеоконференций.
Нашел на просторах интернета MCU Media Server и мануал по сборке, но на первых же шагах столкнулся вот с эти.
OS Centos 7.
Необходимо установить Apache TOMCAT SIP-SERVLET:
# yum install -y maven git ant subversion
# cd /usr/local/src
# git clone https://github.com/RestComm/sip-servlets.git
# cd sip-servlets
# cd ./build/release
# ant -buildfile ./build.xml
Запускается долгий процесс.
Результат такой:
[exec] [ERROR] Failed to execute goal on project sip-servlets-core-api: Could not resolve dependencies for project org.mobicents.servlet.sip:sip-servlets-core-api:jar:3.0.0-SNAPSHOT: Failed to collect dependencies for [org.mobicents.servlet.sip:sip-servlets-spec:jar:3.0.0-SNAPSHOT (compile), org.mobicents.servlet.sip:sip-servlets-jruby:jar:3.0.0-SNAPSHOT (compile), org.mobicents.servlet.sip:sip-servlets-client:jar:3.0.0-SNAPSHOT (compile), org.mobicents.servlet.sip:sip-servlets-annotations:jar:3.0.0-SNAPSHOT (compile), log4j:log4j:jar:1.2.17 (provided), javax.sip:jain-sip-api:jar:1.2.0 (provided), javax.sip:jain-sip-ri:jar:[1.3,1.4) (provided), org.mobicents.javax.sip:restcomm-jain-sip-ext:jar:[1.4,1.5) (provided), org.mobicents.ha.javax.sip:restcomm-jain-sip-ha-core:jar:[1.5,1.6) (provided), junit:junit:jar:3.8.1 (test), javax:javaee-web-api:jar:6.0 (provided)]: No versions available for org.mobicents.javax.sip:restcomm-jain-sip-ext:jar:[1.4,1.5) within specified range -> [Help 1]
