I live in Samoa where the ping delay to my VoIP server is about 850 ms. Most VoIP applications set the T1 SIP timer to 500 ms but this causes a 401 Unauthorised error on registration with my VoIP service. This problem disappears if I can set the T1 timer to greater than 900 ms (I have my Sipura 3000 set to 1.5 sec). Is it possible to set the T1 timer on Express Talk? Ian.
