Hi, I configured asterisk on redhat linux 9 box. I installed two
different ip softphones (SJPHONE
and X-PRO) and got them registered with asterisk. The call from one phone to
another does get routed via asterisk, but there is one problem coming up. As
soon as call is accepted by the end user , it is
automatically disconnected with the error “cannot align media streams”.
If I enable SIP debugging on asterisk, then I find the following output “-- Got SIP response 500 "Internal
server error (cannot align media streams)" back from 197.7.75.129” followed by the following debug
message (no NAT) to
197.7.75.129:5060
-- SIP/2001-a513 is circuit-busy == Everyone is busy at this time We're at 197.7.75.85 port 16816 Answering with preferred capability 2147483647 Answering with non-codec capability 1 Reliably Transmitting (no NAT): SIP/2.0 200 OK Below is the configuration of asterisk SIP.CONF [general] port = 5060
