[asterisk-users] early media issue from phone co.

[Edwin Lam]

hi folks. i have the following puzzle:

when i call certain cell phone# using a regular phone & POTS.
the called cell phone co. usually return a message such as
phone travel out of range or phone is busy etc. if the phone is
unreachable. now when i have the following setup:

sip phone -> asterisk -> PRI -> phone co.

i call the same cell# and if it's unavailable. the PRI return
cause code 31 and hangup, asterisk will then send a SIP BYE to
the sip phone and the channel will simply hangup. how do i
get the message on the sip phone?
