Dear All I have installed Asterisk on my centos 5.0 and I have two other centos 6.0 and centos 5.6 with ekiga sip client. The centos 6.0 can make successful sip calls but centos 5.6 cannot. Among the Asterisk logs, I found that the centos 6.0 has ekiga 3.2.6 but centos 5.6 has ekiga 2.0.2 . How can I install/upgrade my older ekiga? Thank you
