Does it possible to send custom ringback tone to caller for incoming call via SIP trunk to CME ? Similar to ATA186 SIP "ConnectMode" bit19 feature? Which means the caller will hear the CME generated ringback tone rather then the telco ringback tone?

This is a hidden dial peer command that you can try:


progress_ind alert strip 8

Try it out, however the incoming SIP dial-peer doesn't allow "progress_ind".


I tried on outgoing dial-peer, and seems like no effect.


Are there anything else I can try ?

You can try taking the 8 off the last command.


Otherwise, I don't know of any other commands that can accomplish this. This command is typically used on pots legs, so it may not work for SIP trunks.
