CallerID problem during call transfer. #1

Closed rranjan-rly closed 1 year ago

rranjan-rly commented 2 years ago

The test setup has CoreIP T27G phones. Let us say there are three users A, B and C. The scenario is explained below.

  1. A dials B -> The caller-id displayed at phone B shows A.
  2. B transfers this call to C. The caller-id displayed at C shows B and not A in both the cases of attended as well as blind transfer.
  3. The result desired is that caller-id of A must be shown to C.

Sir, I will try this on Grandtream GPX1625 phones and share the observations.

Sir, Observations by using Asterisk server & Grandstream GPX1625 IP Phone. attended Transfer:

  1. A-> dials B -->caller id at phone B shows A. B->> answers the call
  2. B-> press hold. A--> gets MOH, B-> dials C the caller id is shows B
  3. C-> answers the call. B>> can now toggle between A & C by putting either of them on hold. since B has already informed to C about the call from A , so sending caller id of A to be shown on C seems irrelevant.
  4. B -> presses Transfer key A & C both are on MOH.
  5. B-> evoke Hold key and call gets transferred to C.
  6. A & C are in Talk mode. B becomes idle. Blind Transfer
  7. A dials B -> Caller id displayed at B shows A
  8. B -> answers the call & press Transfer key ( in attended transfer its hold key). A gets MOH.
  9. B -> dials C. caller id displayed at C shows A . ringing start at C & A gets RBT (MOH is stopped) and B becomes idle. all the three actions >C start ringing, RBT to A (MOH is off) & DEVICE_STATE B is idle.
  10. C answers the call. A&C are talk mode with caller id at C shows A. Call Forward:
  11. A dials B --> caller id displayed at B shows of A. B rings.
  12. B -> without answering the call, choose to forward the call to C thus presses 'Forward' key ( 'Forward' option is displayed on display of phone B. B presses the corresponding key to forward the call)
  13. A -> gets continuous RBT. ringing continues at B
  14. B --> in Ringing condition presses Forward key (dial option for B is evoked) and Dials C
  15. C -> gets ring with caller id displayed at C shows A.
  16. A -> continues with RBT, C is ringing & DEVICE_STATE of B is idle.
  17. C -> answers the call.
  18. => A & C are in call.

Hi,

Did you do this test on a bare Asterisk configuration or the configuration generated by the code?

The Yealink phone was not honoring the P-Assert-Identity (PAI) in its default configuration. The phone configuration was changed to add the line account.1.cid_source = 2. This enables the PAI and the phone is now showing the correct CLI when we transfer a call.

Closed.
