I have IPCCX6.0 with CCM4.3, users using IP Phones with CAD.
In my setup on the IP Phone the DID line is a 4-digit extn, say 2536(office IPTEL Setup), the IPCCX extn is second line on phone say..536.
I am facing the following problems:-
1)When I dial 536 from phone with primary line 2535 & IPCCx line 535,,, I notice a huge delay before the call starts ringing on 536.
2)when I try to add the supervisor extn say 535 from 536 in the conference , when 536 is already in call with customer,
again there is huge delay(strangely now I am using CAD).
3)Calling 535 to 536 from IP Phone ..same problem... huge delay
Strangely, if I dial from CAD from extn 535 to 536, the call rings immediately.
It seems to me the IP Phone is using for timeout , but no problem is for 4 digit extention dialing(which is the DID lines as per office IPTEL Setup).
The Office Phones(DID lines) and IPCCX extn use the same Partition and CSS.
I even tried to create a different CSS and Partition for the ipccx etn, but no improvement in delay.
Not sure this is a CSS/Partition problem,,, or interdigit timeout.
