I had this issue with telekom VoIP/DSL Connections. I think it is the same issue.
You see many entries per second in "fw ctl zedebug drop | grep fwconn_key_init_links " if the issue occure.

Hi Silvia,
Rules:
Incomming > original SIP service > from provider VoIP server to internal VoIP server
Incomming > udp range RTP (from 1025 to 65535) > from provider RTP server to internal RTP server
Outgoing > original SIP service > from internal VoIP server to provider VoIP server
Outgoing > udp range RTP (from 1025 to 65535) > Drop
Regards
Heiko

At first I thought it was a problem with the Telekom in Germany. Now I think it's a fundamental problem with VoIP and RTP.

Outbond > Drop all high ports as range?
Is this correct?
