Hi Somen,
There are many Gateway which use 183 Session progress for Error playing when PSTN side phone are switched off or some other error reason. Not sure about list of devices which plays these Tones. But it is very easy to implement using 183 Session progress Response. For example a UAS OR State full proxy (with Media server capability) can give 183 Session progress and start playing any file. Once the call got established with 200 OK, stop file playing. Regards, -- Vishal Mathur Manager - Applications Group Netyantra India Pvt.
