I have a situation that I didn't configure but I'm trying to get it to work. In short, I have a CUC 7 server handling VM for several CME sites. At the central site we're using a 2851 to relay MWI indicators via SIP to the other CMEs. This process stopped working at some point and now all lights are either stuck on or off. I believe the configuration is correct, I've followed the cisco doc: http://www.cisco.com/en/US/docs/voice_ip_comm/uc_system/UC5.0.2/ipt_system_arch/UC05_CME.html#wp1065240
If I run a debug ccsip error on the mwi relay server i get constant errors: //-1/DF7420AFA53C/SIP/Error/sipSPIUaddCcbToTable: Could not add to table. Key is NULL.
//-1/DF7420AFA53C/SIP/Error/sact_idle_new_message_register: CCSIP_REGISTER:: Problem adding CCB to UAS Table
on the relay client i get this error: //-1/xxxxxxxxxxxx/SIP/Error/HandleUdpSocketWrites: Send failed errno 261
Has anyone configured this and could provide some insight. I want to just reboot the routers, but this isn't an option at this point. Can I restart the sip service on the routers?
