Hi,
I just started with setting up a new asterisk system, that will operate on a
sip trunk, but I wonder, how to transfer the calls to different extensions,
because all calls appear as being send to the base number of the trunk.
E.g. given the trunk range of 1234567800-12345678099, a call to 1234567800 is
matched by the same pattern as a call to 12345678099.
; matches 12345678099, too
exten => _1234567800,1,Dial(SIP/int)
Except from SIP invite with tcpdump:
INVITE sip:123456780000@provider:5060 SIP/2.0
From: <sip:013579246800@provider>;tag=as6bc7cbbc
To: <sip:1234567800099@other:5060>
I wonder, if I really need to grab the extension with
Set(DN=${SIP_HEADER(TO):5}) or something similar?
Another issue is, that I don't like asterisk to decline foreign INVITE
requests. Any best practices from within asterisk on how to ignore SIP
invitations, that don't match certain criteria (neither local nor from sip
provider)?
System: openSUSE 42.2, Asterisk 14.5.0
Thanks in advance,
Pete
