[asterisk-users] Filtering duplicate RTP packets

[Boris Bakchiev]

Replying to myself.... 

Its fixed now....

 

Checking timestamps is optional according to RFC so asterisk is not
doing it.

Anyway, I made a patch and tested it and its working.

 

Thanks.

Subject: [asterisk-users] Filtering duplicate RTP packets

 

Hi,

 

I have a SIP provider who sometimes sends duplicate RTP packets to me.

 

Sent RTP packet to      10.55.20.201:17440 (type 08, seq 008536, ts
4846560, len 000160)

Got  RTP packet from    10.55.20.201:17440 (type 08, seq 051978, ts
3647104992, len 000160)

Got  RTP packet from    10.55.20.201:17440 (type 08, seq 051979, ts
3647104992, len 000160)

 

Sent RTP packet to      10.55.20.201:17440 (type 08, seq 008537, ts
4846720, len 000160)

Got  RTP packet from    10.55.20.201:17440 (type 08, seq 051980, ts
3647105152, len 000160)

Got  RTP packet from    10.55.20.201:17440 (type 08, seq 051981, ts
3647105152, len 000160)

 

 

Unfortunately they're unable to filter it because this is the way they
receive it themselves.

 

Can this be fixed within asterisk with a custom patch? <hint>

 

Kind regards
