My ISP blocks SIP traffic (port 5060). Can I use an alternative SIP port?

Yes, every SIP node has an alternative SIP port 1221. 

You can configure the SIP devices to use the port 1221 instead of the port 5060.

Please note, it can help to overcome the issue only if your ISP blocks the traffic based on the port and will not help if they use the Deep packet inspection (DPI) technology.
