[asterisk-dev] Zap outofband busy indication to mobile networks

[Tristan Graham - Skymarket Ltd]

Hi Paul,

Had tried that method as well and it seems to have the same issue - in
terms of PRI the traces are virtually identical (equivalent to forcing
out of band even when default is in-band). Land line again has regular
engaged tone, mobile gives same three beeps followed by hangup rather
than busy followed by hangup.
