T21p / T19p - registration fail - helps changing local SIP port

[kakaki]

On both models there is problem.
Phone's work correctly for 2-4 days.
After that period on both phones there is registration failed, doesn't help forcing to register or rebooting device.
Registering takes about 30 second to show failed (look's like there is no answer).

After changing local SIP port from 5061 to 5062 registers immediately, on next fail changing backward from 5062 to 5061 helps.

Both model have latest firmware 31.72.0.75, on previous version problem also existed.

I have dynamic public IP that changes every 24 hours from Internet provider, could this be problem with registering device on SIP provider?

Part of logs on first reg fail, there is error with "reg acc"

Does the T21 or T19 have a secondary SIP Server option that it can fail to? I do not have one to login to right now.
On server one - use port 5061
On server two - use port 5062
Ensure both ports are open to firewall.

BTW: You might want to obfuscate your public ip address.I know it is dynamic... but in the meantime, it could be current.

[kakaki]

There is no secondary connection set (SIP Server 2). provider only has one domain available.
Port 5061/5062 is for LOCAL not remote (settings in Account-advanced-Local SIP Port)

There is no public IP address visible only local and IP of VOIP provider halonet.pl

Do you have multiple endpoints assigned in the same building?I think I read the above as YES.
Does each phone us a different internal port?
