spa 303 - no RBT during 183 session progress

[FabienEVOX]

Hello,

I am using a phone Cisco SPA 303 with my own SIP account (Asterisk).

When I call any number, there is no ringback tone played during 183 session progress. I can hear RBT if I receive 180 ringing message from remote endpoint, so is there any setting to make in order to generate RBT with 183 SP ?

Thanks.

Generate RBT by whom ? By SPA303 ? No, SPA303 never respond with 183, so it need not to generate ringback tone by self.

You didn't disclosed who is generating the 183. I assume it is the Asterisk. In such case, you are asking for Asterisk settings - and in such case you may consider to ask in more appropriate forum.
