We have had the same problem with telecom in Germany for 3 months. Does this setting also help here?

[R89_99]

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

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?

[Hanko_Alderson]

The same issue in UK:-( 

[R89_99]

Yes, drop all outgoing RTP traffic.
