How To Configure ScopTEL with NAT (Network Address Translation)

ScopTEL includes a SBC that does a very good job of handling NAT’d extensions and trunks when the peer supports RPORT.

This article covers the recommended configuration for ScopTEL and NAT.

  • ICE/STUN/TURN are not mandatory and aren’t recommended
  • There are mandatory settings when ScopTEL is not exposed directly to the Internet on its public interface and its sitting behind a third party NAT router. This article does not cover third party router configurations or port forwarding requirements.
  • The default ports used for ScopTEL SIP traffic are:
  • udp/5060 (used for UDP SIP signalling traffic)
  • tcp/5060 (used for TCP SIP signalling traffic)
  • tcp/5061 (used for TLS/SRTP SIP signalling traffic)
  • udp/10000-20000 (used for UDP SIP RTP traffic)
  • tcp/10000-2000 (used for SIP SRTP traffic)

Managing Backups for Multiple ScopTEL Systems

  • ZIP and tar and 16 bit applications and are therefore limited in creating a maximum file size of 4Gb. Therefore if the compressed backup will be larger than 4Gb the backup will be truncated due to the limitations of these 16 bit applications.
  • Remote backups to FTP servers can be difficult due to NAT issues. If the ScopTEL server is behind NAT and the remote FTP server is behind NAT it is doubtful that the remote backup will succeed due to the number of dynamic ports that must be allocated for the file transfers.
  • Local Backup (File) is not a recommended backup Destination in the ScopTEL Backup Manager because it will create a local backup file each time it is executed and this can result in low drive space.
  • If you are backing up a server in order to migrate to another platform it is highly recommended you use the method published in our knowledgebase at https://blog.scopserv.com/2018/10/putty-and-winscp-backup-and-restore-method/ the purpose of the document you are reading is to schedule remote backups especially if you are an administrator trying to automate backups for multiple remote systems.
