Part 28 About Sip - Tieline ViA User Manual

Important Note: Routing configuration is unsupported on Tieline G3 and non-Tieline
codecs. Configure a POTS Answer Route to direct incoming calls to a matching Answer
program route. Note: If there is a mismatch between the POTS Answer Route and an
Answer program route, the call can still connect and routes are ignored.
Reset POTS Answering Settings
To reset POTS answering settings to factory defaults:
1. Press the HOME
2. Navigate to Answering and then tap POTS Answering
3. Tap Menu
Answer Config.
4. Tap in the confirmation dialog to revert to factory default settings.
28 About SIP
SIP provides interoperability between different brands of codecs due to its standardized protocols
for connecting different devices. The codec is fully EBU N/ACIP Tech 3326 compliant when
connecting using SIP (Session Initiation Protocol) to other brands of IP codecs.
SIP is also a useful way of dialing another device and locating it easily. This task is usually
performed by SIP servers, which communicate between SIP-compliant devices to set up a call. SIP
connections can be made in two ways; registered or unregistered.
Unregistered Peer-to-Peer SIP Connections
Codecs don't need to be registered to a SIP server to dial peer-to-peer SIP connections. An
unregistered SIP peer-to-peer connection involves two codecs connecting to each other directly
using an IP address, as you would for a standard Tieline IP call. The difference is that a Tieline IP
call uses proprietary Tieline session data to negotiate call parameters (e.g. algorithm and bit rate)
when a call is established, whereas a peer-to-peer SIP connection uses Session Description
Protocol (SDP) for this purpose. SIP provides interoperability between different brands of codecs due
to its standardized protocols for connecting dissimilar devices and is used when connecting Tieline
codecs to non-Tieline devices.
