-----------------------------------------------------------------

[^recognize_clip_after_ring.patch] is a patch to chan_mobile.c, that handles RING just like +CIEV: 4,1

With this patch, a channel is opened directly after the first +CLIP response in the above sample. This reduces the waiting time, before an incoming call is reported to asterisk core.

                
      was (Author: heiko.bihr):
    make response sequence RING; +CLIP open an asterisk channel

> My old Nokia 6230i emits the following response sequence for an incoming call
> {quote}
> RING
> +CLIP: "+49xxxxxxxx",145
> +CIEV: 3,1
> +CIEV: 4,1
> RING
> +CLIP: "+49xxxxxxxx",145

> chan_mobile detects an incoming call, if it receives +CIEV. It then waits for a +CLIP response to get the caller id and after that opens a channel.
> On my mobile, there are 4 seconds of waiting time between the two RING answers in the above sequence. These 4 seconds must pass for every incoming call, before it is reported to asterisk.
