SNTP issues

RouterOS General
1

So I came across this interesting problem the other day. I have SIP phones running at my office. In there cfg file where they are supposed to get the SNTP addreess. Sometime ago i noticed the time no longer correct. After much frustration I found the phones were pulling the SNTP address off the mikrotik sntp client address even though it is not enabled. Several things in my testing.

  1. If I set my phone to a static Ip address then it pulls the correct sntp address from its cfg file.
  2. If is set my sntp clinet in the mikrotik to 0.0.0.0 and leave my phone on dhcp then it will pull the correct sntp address from it cfg file.

Anyone have any thoughts as to how I can have a SNTP client address in my mikrotik so its time will stay correct, but have it not interfere with my phones which i want to keep in dhcp mode.

Use /ip dhcp-server network export or in winbox IP->DHCP Server->Networks.

The phones get the SNTP address from DHCP, even if the server is not enabled, so check your ntp server settings there.
