Hi,

Our custom application sets some SIP headers that we want passed to the
called party via asterisk in a simple proxy setup. It works fine for
voice calls, but we also use SIP to send outofcall messages. I notice I
can't use SIP_HEADER() to get those custom SIP headers in outofcall
messages. Is this a bug?

I have this in sip.conf:

[general]
accept_outofcall_message=yes
outofcall_message_context=astsms

We can send and receive messages between extensions with this without
issue. In extensions.conf:

[astsms]
exten => _X.,1,Set(CHATNOSTORE=${SIP_HEADER(X-Semo-ChatNoStoreForward)})
exten => _X.,n,NoOp(CHATNOSTORE ${CHATNOSTORE})
exten => _X.,n,SIPAddHeader(X-Semo-ChatNoStoreForward: ${CHATNOSTORE})
[snip the parts that actually send on the message]


CHATNOSTORE gets set to "", even though I can see the header in a packet
trace:


0x0260: 654f 7267 3a20 6865 6c6c 6f0d 0a58 2d53 eOrg:.hello..X-S
0x0270: 656d 6f2d 4368 6174 4e6f 5374 6f72 6546 emo-ChatNoStoreF
0x0280: 6f72 7761 7264 3a20 666f 7277 6172 645f orward:.forward_
0x0290: 7661 6c75 650d 0a0d 0a54 6573 7420 6d65 value....Test.me
0x02a0: 7373 6167 6520 31 ssage.1

I'm not sure where to take this next... dive into the code for SIP_HEADER?

Thanks,

j
