At this point you can click Save Program and save the program with default algorithm and jitter
settings. Alternatively, click Next to confirm and specify algorithm and jitter settings for this
connection and configure backup audio settings (recommended).
Important Notes:
· The default UDP audio port when using SIP for a peer-to-peer connection is 5004 in
Tieline codecs. To contact a codec that is behind a firewall or NAT-enabled router, it is
essential that this and all other relevant ports are open and forwarded to the other device.
· Tieline codecs automatically add "sip:" to the address you enter in the Address field
when dialing, so it's not necessary to add this.
· Enter the IP address or SIP URI, then a full colon and the session port number to change
the session port from the default setting 5060.

· Alternatively, select a Fixed Buffer Level and enter the Jitter Depth, which must be
between 12ms and 5000ms depending on the algorithm you select.
· RFC-compliant FEC can also be configured if required and the percentage is configurable.
