Owner Compute is compatible with most SIP Phones.
Linphone is the recommended SIP software if you do not have a preference.
We have some notes on how to configure Linphone for Owner Compute:
Owner Compute requires the use of up to four SIP variables:
From Header
The original caller's number, if NO forwarding otherwise it is the forwarder's number.
ANI variable in Asterisk
P-Asserted-Identity
The TRUE original caller's number to the destination, even if the "From" header is changed.
ANI variable in Asterisk
Diversion Header
This header tells the receiving party that the call was redirected/forwarded and contains the number of the person who forwarded the call.
RDNIS variable in Asterisk.
To Header
The final destination number (the person being forwarded to).
DNIS variable in Asterisk.
Read pjsip
exten => s,n,Set(RAW_FROM=${PJSIP_HEADER(read,From)})
Read chan_sip
exten => s,n,Set(RAW_FROM=${SIP_HEADER(From)})
Read pjsip
exten => s,n,Set(MY_PAI_HEADER=${PJSIP_HEADER(read,P-Asserted-Identity)}
Read chan_sip
exten => s,n,Set(MY_PAI_HEADER=${SIP_HEADER(P-Asserted-Identity)})
Write pjsip
same => n,Set(PJSIP_HEADER(add,P-Asserted-Identity)=<sip:123456789@yourdomain.com>)
Write chan_sip
same => n,SipAddHeader(P-Asserted-Identity: <sip:123456789@yourdomain.com>)
