[cisco-voip] VG224/VG248 with PLAR/CUCM behaviour after far end hangs up.

[Lelio Fulgenzi]

OK, I just confirmed that the following config works while registered with CUCM as well as during SRST. For some reason, it didn't work when I tested it a few days back. So at least I have an alternative. 

But man, that VG248 behaviour still surprises me.

sccp plar 
voiceport 2/0 dial 57555

OK, this started off as a simple why doesn't this work on a VG224, but when I tested it on a VG248 things got weird. 

First off, VG224. 

When I configure a VG224 port via SCCP with CallManger (v4.1 and v7.1 confirmed) and have PLAR working (blank translation in partition style), if the far end hangs up first after the initial PLAR, the VG224 port gets dialtone for a bit, then immediately starts the dial process again. 

When I configure the VG224 with PLAR for SRST, this does not happen. When the far end hangs up, they simply get dial tone. This is the behaviour I'd like to see (and expect?) during CCM operation. 

OK, now for the VG248. 

When I configure a VG248 port with CallManager (v4.1 confirmed) and have PLAR working as above, if the far end hangs up after the initial PLAR, the VG248 gets dead air, then eventually gets error tone. The far end IP phone starts acting all screwed up, like it's trying to ring from the VG248 port, but it's all static-y and stop/start. One phone had 290 missed calls by the time it stopped. Others I've had to unplug and plug back in. 

I'm using older phone loads on the 7940/60s which could be the problem, a 7912 seems to behave a little bit better (but not much). 

Thoughts?
