Does anybody has any tips on how to avoid being blocked by SIM or IMEI number by the GSM operator using a Orion Telecom Voip GSM gateway 30 channels?

Thanks for your help.

The VoIP Blocking can totally be solved by using VoiceGuard@ which is not VPN based ones.
VoiceGuard@ controls and monitors full voice signaling and media flow intelligently, meanwhile disguises sip and rtp packets into normal allowed data packets such as DNS and TFTP, and makes two-way encryption and decryption driven by user-customized policy.
VPN maybe be blocked because VPN use standard port such as PPTP 71, L2tp 73 or IPSec. However, VoiceGuard Control Protocol (VGCP) does not use fixed port either for TCP or UDP.
What's more unlike VPN based products VoiceGuard@ donot take any bandwidth or cost heavy overhead.
For more information, add my MSN in the list.
