    Using a GXP1450 that worked up until today. No changes made.

    First inbound or outbound call works fine. All calls following do not even get to pbx. phone just sits and does nothing.

    Inbound calls to this phone will just time out and go to voicemail.

    wireshark shows nothing. The phone is not even trying to make a call after the first call.

    Any Ideas?

    Hi, Have you tried to re- provision the phone?

    Assuming the phone is registered, look at the IP address and ensure that it is not in use by another device. Look at the IP on the phone and then disconnect it and try to ping it. It there is a response, then another device also is using that IP.
