Mitel 5330 in SIP mode not updating time from NTP

[zax123]

Hi all,

I've converted a bunch of Mitel 5330 handsets to SIP.  I have set the NTP server to a whole bunch of different things (straight IP addresses, FQDN entries) and they don't seem to update the time on the display.

I've even tried updating the NTP server address in the web interface of the phone to no avail.

I was just wondering if anyone else has experienced this and may have a magical solution.

Thanks!

Robert

We use pool.ntp.org or set the timeserver in DHCP option 42 & GMT offset in option 2.

Yeah, I tried pool.ntp.org and a bunch of other IPs/domains and no luck.  Very bizarre...

Hmm... have you wiresharked it? Are you sure the phone is trying and that is using the proper gateway?

Wireshark is a VoIP tech's best friend.

I guess I'll have to wireshark it.  Not sure how often it makes an SNTP request, but I'll just wireshark a boot up sequence and see what I can get.

This sounds like a gateway issue. The phones may be on a vlan where they cannot properly get out to the internet and reach pool.ntp.org.
