MWI Relay in CME / SRST mode - 3 questions at the end
I'm running into a point of confusion and am wondering if someone can clarify:
CUE - CUCM integration working just fine.
Rolled over to CME/SRST mode and was unable to refresh MWI to the SCCP / SIP phones.
One Issue I found in my CUE config is that the following trigger was getting configured with the wrong IP it seems. My CME / SRST IP address is 126.96.36.199 (Loop 0 I believe)
ccn subsystem sip
gateway address "188.8.131.52" (loop 1 I believe)
MWI SIP unsolicited
This is the IP that the system configures from the CUE initialization wizard, but it wouldn't work until I changed it to 184.108.40.206.
One of the things I thought I may have missed, but it doesn't seem to actually make a difference is the 'mwi sip' command under the srst ephone-dn-template. I've rolled back with and without the template applied and it works (as long as I have the gateway addy set to 220.127.116.11).
Other configured key items already exist:
mwi-server ipv4:18.104.22.168 unsolicited
so I have 3 questions:
1) is it the case that MWI does not play nicely for SIP phones in SRST mode or am I seeing dated documentation...i.e. SIP and MWI should be working properly.
2) is the mwi sip a necessary component or does it add some stability (meaning, do it either way), or does it perform some ancillary function that I'm not aware of. It seems like it's only for subscriber-notify MWI and not for unsolicited.
3) why, when I do a factory default, does it configure my gateway address as the loopback physical IP and not the SCCP address of CME? Do I need to go back in and fix that on lab day or is there something squirrely on my config?
