I upgraded a 2801 router from 12.4(24)T6 to 15.1(3)T2 and SCCP SRST stopped working (I've also tried 15.1(4)M2). It works fine on 12.4, but with 15.1, the phones never register. Debug ephone detail produces no output at all. The config is pretty basic.
max-conferences 4 gain -6
ip source-address 192.168.244.1 port 2000
Am I missing something? I know on a 2900 platform I need to add a license, but I was told by TAC that on the 2800 I do not. Is that incorrect?
Thanks for the response Alex. I already turned the trust list off with "no ip address trusted authenticate" but it didn't make any difference. I thought that only affected SIP and H.323 connections. The problem is the phones never register. Surprisingly, SIP phones work fine even without the trust list turned off. It's only SCCP phones that don't register.
