New Zealand Telepermit
Polycom SoundPoint IP560 VoIP Telephone PTC 220/08/009
PTC General Warning
1. The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has accepted that the
item complies with minimum conditions for connection to its network. It indicates no endorsement of the
product by Telecom, nor does it provide any sort of warranty. Above all, it provides no assurance that any item
will work correctly in all respects with another item of Telepermitted equipment of a different make or model, nor
does it imply that any product is compatible with all of Telecom's network services.
Echo Cancellation
2. Echo cancellers are not normally required in the Telecom PSTN because geographic delays are acceptable
where CPE return loss is maintained within Telepermit limits. However, those private networks making use of
Voice over IP technology are required to provide echo cancellation for all voice calls. The combined effect of
audio / VoIP conversion delay and IP routing delay can cause an echo cancellation time of 64 mS to be
required.
PTC220 Paragraph 8.3.1 Digital Telephone Loudness Rating
3. This Polycom SoundPoint IP560 VoIP Telephone was made to comply with PTC220 paragraph 8.2.1 by
installing a New Zealand specific version of software known as 3.1.0.5891. All samples of this telephone
connected to the Telecom network must have this software version installed to be fully compliant with this
Telepermit.
