SIP & RTP Ports Range

[Hamidsattarrana]

Hi,

I have a situation where I have to VOIP Server (Vicidial Asterisk) on cloud. And locally we have client behind the Cisco Router 3825.

We have 2 Internet Connections. One for Voice another for Data.

I want to route all RTP & SIP Traffic only to VOIP to Voice ISP. How can i do that?

I am thinking about configuring an ACL and match the SIP & RTP Ports and then use Route-MAP for next hop (Voice ISP)...

I am not sure about which ports should I match with ACL?

Or is there any other way to match RTP and SIP only so that they can go via Voice ISP?

Thanks.

On a router, NBAR might be able to match RTP and/or SIP.

Yes I am able to match RTP and SIP. Can you share the whole configurations?

If all SIP/RTP has to go through VoIP Server, you can configure a static route to Server via ISP1 and a default route to ISP2.

HTH.

No we also have http traffic.
