Can someone help?
I configured SX20 behind firewall with NAT. I can call in, but cannot establish outgoing call.
Default Call Protocol
The default call protocol is set to H323, but system is not registered on that protocol. The system may not be able to make any calls. Please eitherchange the default call protocol, verify that the protocol is enabled, or verify the H323 configuration..
My H323 NAT is on, CallSetup Mode is Direct, PortAllocation is Dynamic.
You can also verify if the NAT mode is set to "ON" or "Auto".
In case you are trying for pulbic IPs, you can set the mode to either, and setting it to AUTO would educate the codec that if any IP in same LAN is called, it would not try to NAT it.
I tested with all NAT options - ON, OFF, Auto. None of them works. I'm experienced with Polycom and know how to test with them. Cisco/Tandberg is still bit mystery to me. Why there is no tracert/ping test in Diagnostics??
Firewall people insist all is working from their site.. I should be able to prove it or tell them what is wrong.
I have problem with firewall, As i configured static nat i can call from sx20 to outside,but from outside nobody can call to me.
my global ip is 126.96.36.199 ,local 192.168.230.104.
can someone help me with my firewall (ASA 5510 ) configuration
According to my colleague you should test to switch off some feature on ASA which is testing inside of packets (like you say dear packat you are SMTP on port 25? Let's look if you realy are SMTP...). He says this is often the case of denying packets.
set the port allocation as static, if it is set to dynamic it will open ports above 11000 range.
ports to be on firewall:
The following ports will cover both MultiSite and H.239 (dual stream):
