[asterisk-dev] strange "new-callerid" on DAHDI

[Klaus Darilion]

Hi!

I discovered a strange new callerid set on an outgoing DAHDI channel 
after the channel is answered. It will be changed from called number to 
the caller's number. This does not happen on outgoing SIP channels.

scenario: Incoming SIP call will be forwarded to SIP or DAHDI (PRI)
Traces: below

1. Is this intended behavior? I searched to code but did not find the 
reason. It is strange that the meaning of the callerid of outgoing 
channel depends on the used technology.

regards
