I have a Nortel CS1000 version 7.5 with SIP trunks connected to a Virtual Mitel 3300 version 12.0.3.15, the Mitel has SIP trunks to a LD provider. Occasionally when making a call from a Nortel IP phone that goes to the Mitel via the SIP trunks and out the LD providers SIP trunks the Nortel phone will time out and say "Release and Try Again". If I call the same number from my Mitel IP phone the call does go through but it does take longer than it should, I am assuming that the LD provider or someone along the line is having a routing issue that slows the connect time down. Is there a timer in the Nortel that could be increased 2-3 seconds to prevent that Release and Try Again message? If so how do you change it?
