Dear all,
Has anybody met this issue:
My lab has a CS1KE 7.5(CPMG), I have deployed it as a sip line gateway, I can register the third party SIP phones and AVAYA SIP phones such as 1120E on the CS1KE, but I found that when I use the SIP phone A, calls the SIP phone B, B answers the call and then transfers to SIP phone C, the call is established and B is released, but I can not see the original caller number(SIP phone A) on the screen of SIP phone C, instead it displays the number of phone B.
If using call forward instead of transfer, no such problem.
B calls C directly, no such problem.
I am aware that some parameters are involved to this issue, and I have tried to change them as below, but the problem continues.
rdb-->ncrd yes
dch--> rcap rd2/rd3 (both are tested)
So can anybody help me for figuring out this problem?
