[OpenSIPS-Users] Transfer issue

[Flavio E. Goncalves]

Hi Peter,

You need to have support for REFER in all the SIP components, UACs 
and Gateways. Your SIP provider seems to be refusing your REFERS with 
the message "501 Not Implemented". The only way to workaround (as far 
as I know) is to use a gateway before your SIP provider that 
implements the REFER messages. You can do this using Asterisk. Handle 
the REFERs in the same way you do with INVITEs, there is a parameter 
called allowexternaldomains and it needs to be set to yes. The 
security for REFERs is the same as the one used for INVITEs.

Regards,

Flavio E. Goncalves
