[SIPForum-discussion] SIP port 5060 blocked

[Brecl, Peter]

Your device registers FROM a port that may or may not be port 5060 (if you have NAT). However, your VoIP service provider will be expecting incoming traffic on UDP port 5060 (i.e. your traffic sent to IP destination address with UDP port 5060). Your ISP probably setup a rule to block outbound (destination) UDP (and likely TCP) port 5060. You would need to check if your VoIP provider can listen for SIP traffic on other "non-standard" ports (other than 5060).

BTW - what is the ISP name that is blocking VoIP traffic?

Probably time to change the ISP (if you have that option).

You can use any port you want provided that port is registered with the SIP proxy.

 

Since so many people are behind NAT anyway it's common that people register ports that are not 5060.

Dear forum members ,

 

I am based in Oman and recently our ISP has blocked the common SIP port 5060. I use a hell a lot of VoIP using the SIP based services and I feel crippled now . 

 

In the meanwhile , I have informed my SIP - VoIP service providers also and they are also finding out a solution for SIP users. 

 

I would like to know , what are the commonly used SIP ports and is there any software to scan the unblocked SIP ports by my ISP.

 

Your information on this topic is highly appreciated .

 

Dixen.
