Hi, I'm having trouble using "Ringing" with a SIP client. I'm trying to give the caller the impression that the line hasn't been answered, whilst listening for various extensions to be dialled. Here's is the extension: exten => s,1,Wait(1) exten => s,2,Answer exten => s,3,DigitTimeout,3 exten => s,4,ResponseTimeout,5 exten => s,5,Ringing There are various extensions that can be dialled. For example, I have one that calls another SIP target. I've got two problems: The first is cosmetic:- is there any way to get the Ringing to work like Background, and turn off the Ringing indication once digits start being dialled? The second is a show-stopper, though: As soon as Asterisk tries to connect to another SIP destination, I see in the log: WARNING[27662]: File chan_sip.c, Line 957 (sip_write): Asked to transmit frame type 64, while native formats is 4 (read/write = 8/4) And Asterisk drops the connection. Any advice for me? Steve
