Add PAID to UPDATE
Hi Guys,
Been struggling for the last week or so to write a rule that copies the whole PAID header from an Invite response (18X/200) and place it into any subsequent in-dialog UDATEs that are received.
UAC makes a call and is provided called ID detail in the form of Display name and number by the UAS in the PAID of the 18x/200
UAC --> SBC --> UAS
Initially I built a rule-set that copies pertinent information from the UPDATES FROM header (only for certain MAC address ranges) and adds a PAID based on this detail. This seemed to work initially however when fully tested in the lab it was evident that on certain call flows the UAS's FROM header in the UPDATE didn't exactly match the PAID received in the 18x/200 responses causing a change in CLID on receipt of UPDATE. UPDATEs are sent by the UAS every 10 minutes as a form of session refresh/audit.
