Re: [Opalvoip-user] RE-REGISTER failure since opal 3.10.7

[Robert J. <ro...@vo...>]

Can you send me the full log file? Level 4 please.

In particular I am looking for a line like 'Authentication already 
performed using current credentials, not trying again".

Send to my direct e-mail please, the list has a size limit to postings.
