SRST

In SRST mode an incoming call from PSTN E1 pri ---1760--->IP phone user anwers phone the 2 parties chat for a while.Then the IP phone user says hold on bob I'll tranfer you to charlie another Ip phone user.

scenario 1

Charlies phone rings and Charlie anwers they have a chat everything is good.Both parties hangup

scenario 2 Charlie doesnt answer as he is out of the office. So PSTN user hangs up.The issue here is charlies phone keeps ringing.

The call is gone as far as ISDN is concerend normal call clearing.

Why doesnt the skinny tear down the call anyone know of a bug IOS 12.2 15T2 1760 ?

In SRST mode as well ANI is not passed to the phones is this intelligence built in to any version of SRST ?

Ok next I want to went apply a "voice" translation rule 1 1-15rules under call-manager-fallback can this be done in version 3.The reason being is voice translations (not documented anywhere I can find)allow a very complex dial-plan to implemented I have tesed several regular expressions with success that dont work with a translation rule though I cant apply this in CCM fallback like a normal translation rule : (

Next question which the TAC couldnt tell me

I want to create CoR for a couple of phones whe SRST mode.

The problem ithe way I see it is that phones register dynamically in srst and a directory number gets assigned a dial-peer first come first served.20001 20096 if i allowed 96 dn max this would be the case.

So how do I apply a Class of restriction ?

The documentation on COR 12.2 2t is absoloute garbage and makes little sense to me .

I'm hoping it can be defined by directory number for example dn 4000

So if someone could give me a working example, one of you Cisco guys must know or have done it or can test it in your lab I would very much appreciate it .
