[asterisk-users] Asterisk outbound register messages causes firewall issues

[Rennes Neps]

Hello!

I have an Asterisk box that has multiple (over 50) individual accounts registering against Ericsson IMS pbx. Problem is, that when there’s a problem in the network, asterisk will retry to register all the accounts at once, causing the IMS to think it is an attack and block the ip. Asterisk continues to bombard the IMS and the block contionues to be applied. To get out of the loop, blocking service on the IMS must be manuallt disabled for some time to allow asterisk to register, then everything works until next time.

My question is, is there any way to make asterisk NOT send all registers at once? Or change source port per account? What is the possible solution, if there even is one?

Thanks in advance
