tabs
• Network Settings parameters:
o Network Jitter Level: extremely high
(Setting the jitter level to extremely high will add extra latency to the
call but will make the voice quality more reliable over most broadband
connections. Unless you believe your internet connection is very stable

12. and does not suffer from high latency or latency variations it is
recommended to keep this level extremely high)
• Proxy and Registration Settings:
o Proxy: 2talk.co.nz

phone number e.g. 028890000)

13. • Supplementary Service Subscription settings:
o If you choose to leave many of the supplementary
services enabled on the PAP2T then the star codes

14. that you use to activate/deactivate services with 2talk
will not work as the PAP2T uses many of the same
star codes and will intercept them when you try to
dial through to 2talk. It is therefore recommended that
you disable some of the key services such as:
 Block CID Serv: no
 Block ANC Serv: no
 Cfwd All Serv: no
 Cfwd Busy Serv: no
 Cfwd No Ans Serv: no
 Cfwd Sel Serv: no
 Cfwd Last Serv: no
 Block Last Serv: no
 Accept Last Serv: no
 DND Serv: no
 Call Return Serv: no
 Speed Dial Serv: no
• Audio Configuration parameters:
o Preferred Codec: G729a

o FAX Passthru Codec: G711a
o FAX Codec Symmetric: yes
o FAX Passthru Method: NSE
o DTMF Tx Method: AVT
o FAX Process NSE: yes
o FAX Disable ECAN: no
NOTE: Since the 2talk FAX service requires that the customer device
support the T.38 fax protocol for reliable IP fax communications and
the PAP2T does not currently support T.38 – you will not be able to get

15. a fax machine working through 2talk using the PAP2T device. We
recommend instead you purchase a Linksys SPA2102 or SPA3102 if you
wish connect a fax machine to 2talk which both support T.38 and are
known to work well with 2talk.

example dial plan you can use.

16. Troubleshooting Tips

17. If you are still having problems getting your PAP2T to register with
2talk then you can try disabling or enabling the STUN settings as
mentioned earlier.
Another thing you can try is changing your SIP Port from ‘5060′ to
‘50600′ in the SIP Settings under each line
Another thing you can try is to change the ‘Proxy’ and ‘Outbound
Proxy’ from ‘2talk.co.nz’ to ‘2talk.co.nz:50600′ in the Proxy and
Registration settings under each line
