Solved: RTP port on UC500

Eivind Jonassen · ‎05-05-2009

Hi,

I´m wondering if it´s possible to setup the UC520 to use RTP ports from 30000 to 30030 only, this is due to a SIP trunk provider who has put the QoS on these ports on the DSL line. We´ve tested this solution on the SPA9000 and it works great.

Regards

There is no way to control the RTP ports on the SIP Trunk of the UC520. The RTP port range is from 16384 to 32767 (even numbered ports only in this range).

You probably need to talk to the SP to ensure QoS on the above port range or rely on other classification criteria such as DSCP

Thanks Maulik,

Since we already solved QoS with RTP ports on the SPA9000 I hoped that the UC520 could use the same setup. We´ll continue testing other methods.

Thanks

Has this changed yet since last post with newer IOS's? we are also looking to narrow down the available ports for firewall and QoS reasons.
