Avaya CM to Avaya IPO via H323

hi all,

i am having a problem.

CM user will call to IPO user. When CM user will end the call while hearing ringback, the phone in IPO continuously ringing.

i already followed the application note from Avaya.

details of the equipments:
IPO r8.1
CM v5.2.1
All analog phones

I have had similar issues - first call works fine, but calls shortly thereafter fail in various ways. I've found that with direct link (no VPN) all was well - hence VPN was the culprit. IP Office to IP Office over the exact same VPN using H323 QSIG had the exact same trouble. Oddly, IP Office to IP Office using SCN worked like a champ. I was able to reproduce this trouble across other VPN connections. Common thread? Netgear routers.

the problem above was solved. i believe checking the enable faststart in H323 line solved the problem.

another problem is, all analog trunk lines was terminated in CM. If outside caller calls a user in IPO and then dropped the call while hearing ringback, the phone in IPO continuously ringing.

when the call is being abandoned, trunk involved (terminated in avaya CM) is not released and the phone (in IPO) continuously ringing.
