[OpenSIPS-Users] presence and dns

Thu Mar 7 04:53:48 EST 2019

Hi Slava,

1) NOTIFY'es

The presence NOTIFY requests are in dialog requests (part of the 
SUBSCRIBE dialog). And a sequential request is sent to a RR or Contact 
URI (from SUBSCRIBE) which typically hold IP addresses - so how do you 
get the @domain.com URI when sending the NOTIFY ? Do you have a SIP 
capture showing the SUBSCRIBE + 200 OK and the NOTIFY errors ?

2) BLF parsing errors - these are 3.0 specific, right ?
