SRST Failback Issue

Hello,

I have a SRST enabled 2821 voice gateway running ios 124.15.T5 which is configured for h323. Version of CM is 4.2.

SRST has been tested and works in the environment however I notice a strange issue with the failback of select phones.

It appears a group of phones (in the same lan) previously registered to SRST are still using their ephone-dn template cfwd no answer, busy etc when an inbound call arrives from the PSTN when CM is back online.

What is strange is the exact same template is applied to a different extension and incoming calls are fine from the PSTN.

I have the below config for SRST:

telephony-service

srst mode auto-provision all

srst ephone template 5

srst dn template 3

srst dn line-mode dual

ephone-dn-template 3

call-forward busy

call-forward noan

pickup-group 1

As I understand the command

srst mode auto-provision all

Should really be set to none.

Could this be causing the issue?

What are the effects of removing the all command and setting to none?

Thanks for your help in advance!
