Both Diversion and Remote Party ID Headers

[s42]

Hi all,

I'm trying configure a SIP Trunk to send originator caller ID on forwarded calls. I've been told (by the provider) that, the invite package i'm sending, must include both diversion and remote caller ID headers with proper info.

They also send me an example invite message which is like below.

Number A calls number B which is on IP Office (9.0.8) and call is forwared to number C

INVITE sip:NUMBER C@XXX.XXX.XXX.XXX SIP/2.0
Via: SIP/2.0/UDP XXX.XXX.XXX.XXX:5060;rport;branch=z9hG4bKfc22fa26e6b11918b023e63f061755ef
From: <sip:NUMBER A@XXX.XXX.XXX.XXX>;tag=5b6a51fee5f9d869
To: <sip:NUMBER C@XXX.XXX.XXX.XXX>
Call-ID: b42314b1536552f96f8ad64c0f9b99f1
CSeq: 1892337829 INVITE
Contact: @XXX.XXX.XXX.XXX:5060;transport=udp>
Max-Forwards: 70
Allow: INVITE,ACK,CANCEL,OPTIONS,BYE,INFO,REFER,NOTIFY,UPDATE
Content-Type: application/sdp
Supported: timer
User-Agent: IP Office 9.0.8.0 build 990
Diversion: <sip:NUMBER B@XXX.XXX.XXX.XXX:5060>;reason=unconditional;screen=no;privacy=off
Remote-Party-Id: <sip:NUMBER A@XXX.XXX.XXX.XXX:5060>;screen=yes

I'm not sure if this is possible just with IP Office.(Maybe it can be done with SBC).

Any ideas ?

Turns out it is not possible with just IP Office. SIP Package manipulation needs to be done to achieve this.

Thanks.

IP Office does not send originating Call ID on forwarded calls. You must use Mobile Twinning.
In your System/Twinning tab make sure you've checked "send original calling party info for Mobile Twinning".
Then setup your users Mobility tab.

I usually set Caller ID on the SIP trunk to Diversion header, not had any issues so far. The send original calling party info for Mobile Twinning I have never used, mainly because before SIP BT didn't offer it so it didnt work, then SIP came out and it wasnt needed.

Andhee's post is all wrong.

"Send original calling party info for Mobile Twinning" is only used when you have ISDN trunks, it should not be enabled on SIP trunks.
Originating Caller ID work on both mobile and forwarded calls.

All SIP providers I've used are fine with just Diversion Header, the number in Diversion Header must be in full national or international format depending on the provider since this is used for validation.
