my vpn.cnf file shows

we have this method working on older phones but am struggling with this model

Dear Mikeļ¼Œ

May i know which old model and firmware the method is working well?

We need you provide the detial llevel 6 syslog files, config.bin and pace trace and the OpenVPN.tar to do debug when you connect the VPN server.
Refer to the FAQ to collect the three files:

Please note, to make a comparision, we need you provide all of the files for both the T29G and the older phones.

Besides, how many phones in total? And how many of them have the issue?
(You can send the files to with link of this post)

thanks Lucia , ive now fixed this - it seemed to be trying to use the second remote address rather than the first so after removing the entry now connected. but now for some reason the account registration fails. Ive tried with the same details on a softphone (VPN > softphone) which works fine. which would be the best log file to trouble shoot the account registration process

If is the refister fail issue, then provide the level 6 syslog, config.bin and pace trace will be OK.
Refer to the FAQ to collect the three files:

BTW, what is the softphone? Can you also attached the syslog of the softphone for us to make a comparision?
