Our company has just installed two Audio Video Servers(AVS), both of these machines are behind a Cisco ASA 5505. The problem is that when the servers are behind the f/w the sessions are not getting initiated. We have opened the following ports(both TCP $ UDP)on the f.w
We contacted the video conferencing software provider, according to them the firewall is blocking SIP.According to them ,since we are located in India we need to do some diff type of setting as the setting for SIP varies according to the country !!.
If this is true then kindly advice on the necessary changes in the configuration and also if the ASA 5505 is the right f/w to be used with AVS.
Thanks in advance
