[OpenSIPS-Users] Presence Contact header

[Aleksandr Chusov]

Hello.
I using presence module on OpenSIPS.
If I correct understand  opensips set Contact header from module param
- server_address, in my case if set I server_address not all client
work ( udp, tcp, tls client ) . If not set opensips set it dynamic but
duplicate transport when send NOTIFY via TCP/TLS. Its normal?
I'm not sure yet fully but maybe with some devices because of this problem.
I will be grateful for any help.

Example:
