Greetings,
I have got a lot of nortel 1140e and I would like to change the firmware from UNIStim to SIP .
I followed the the following topic and I could changed it successfully
/avaya-ip-1100-series-ip-phone-upgrade-to-sip/
The problem is after the phone boots and registers the SIP lines by 1 or 2 minutes I cannot receive calls , the SIP server show the line as unregistered although I can make calls .
One more thing , I would like the phone to auto send the called number , I don't want to press send button after entering the called number.
Please Help
