Hello,
Description of the callflow :
PSTN (066222222) calls CUCM (055711711) -> internal line number 711711.
line 711711 has a CallFwdAll configured to PSTN (047411111)
line 711711 has an External Phone Number Mask configured 055711711
Behaviour :
On the Cisco Cube to the CUCM
Sent:
INVITE sip:055711711@172.16.36.12 SIP/2.0

We see that the CUCM sends the internal phone number in the diversion Header.
-> Diversion: "test" <sip:711711@172.16.36.12>;reason=unconditional;privacy=off;screen=yes
What we would like to have is the following :
-> Diversion: "test" <sip:055711711@172.16.36.12>;reason=unconditional;privacy=off;screen=yes
where the 055711711 is the content of the External Phone number mask
Working on the cube and modifing the 711711 into 055711711 whith SIP manipulation is complicated due to the DN complexity for the customers.
Some discussion talk about configuring a redirect partition and CSS and apply a transformation calling pattern, then use this CSS in the
Redirecting Diversion Header Delivery - Outbound |
Redirecting Party Transformation CSS |
but ... it doesn't seem to work and SDL trace doesn't tell me why ..
Thanks for your hints/help
Regards
Frederic
