How do I find my Codec's User Agent
It may be necessary to discover a codec user agent as some codec manufacturers allow
whitelisting of calls by 'User Agent.' Therefore, it may be necessary to enter a Tieline codec
user agent into a non-Tieline codec to allow it to connect to a Tieline SIP codec.
· From firmware v2.16.xx and later releases the user agent in a Tieline G5 codec is configured
as "Tieline <ProductName> <Firmware Version>". E.g. Tieline Bridge-IT v2.18.68.
· In Tieline G3 codecs the user agent is configured as "Tieline <ProductName> <Serial
Number>". E.g. Tieline TLR350 8972. The model numbers for Tieline G3 codecs are as
follows:
 Commander G3 Rack TLR300 = Model Number TLR300
 Commander G3 Rack TLR300B = Model Number TLR350
 Commander G3 Field TLF300 = Model Number TLF300
 i-Mix G3 TLM600 = Model Number TLM600
Troubleshooting SIP Connections
Manufacturers of professional IP codecs in most cases do not use the standard SIP ports (UDP
5060 and UDP 5004) for making IP connections. Therefore you will need to reconfigure each codec
to use the standard SIP ports in most instances.
Most of the time EBU N/ACIP Tech 3326 SIP compliant codecs should connect when using the
same encoders and connection settings at both ends. However, if one-way audio is encountered, it
is highly likely to be a port forwarding issue. Port forwarding configuration instructions for most
popular routers are available at www.portforward.com.
Some manufacturers support a subset of the EBU N/ACIP Tech 3326 recommendations so not all
algorithms are supported by all manufacturers. G.722 is supported by most codec manufacturers,
so if you encounter connection issues, default to using this algorithm for most troubleshooting
scenarios.
Getting Started with SIP
To dial over SIP peer-to-peer without using a SIP server see
SIP using a SIP Server you will need to:
1. Register the codec to a SIP server using SIP account credentials.
2. Configure a SIP interface in the codec. Note: This SIP1 or SIP2 interface will include the
proxy and port settings, as well as the selected IP interface used to make the connection,
e.g. LAN1 or LAN2.
Common SIP settings Tieline recommends when connecting to non-Tieline codecs like Comrex are
as follows:
· Profile: Mono
· Bit rate: 64kbps
· Algorithm: G.722
· Session port: UDP 5060
· Audio port: UDP 5004
