How do I determine which end is blocking data flow?
Tieline test codec firewalls have the default Tieline TCP and UDP ports open. You can dial into
these test codecs (or other codecs you know are configured correctly) from your recently
configured studio and remote codecs and use the LQ readings to diagnose whether your studio
or remote codec firewall is blocking your data packets. If one codec connects ok and the other
one doesn't, then you will know which end is likely to be causing the problem. As an example:
1. Dial from site 1 to a Tieline test codec.
2. Dial from site 2 to Tieline test codec.
If both of these connect successfully then the “outbound” TCP path for session data is OK, and
the inbound UDP audio path is OK.
3. Dial to site 1 from a codec you know is configured correctly.
4. Dial to site 2 from a codec you know is configured correctly.
If either of these calls fail then TCP and/or UDP inbound data is being blocked on the failed
connection (see "Troubleshooting TCP Port Blocking" above).
Testing your Codec
· Visit www.tieline.com for a list of test IP codec addresses you can use to verify your codec is
configured correctly.
· See Testing IP Network Connections for more IP test information.
