Telco & Point to Point Internet VPN
Q1:
What are the most secure factors to consider when doing the above? IPsec with 3Des?
Q2:
Symmetric or Asymmetric?
Q3:
If we're using Telco's VPN via Internet pipes, the VPN (ie encryption) is done at router or firewall level?
Q4:
For ease of porting to another ISP/public IP address, what do we need to do? Portable NAT?
We used Cisco routers & Juniper fwall

I'm referring to the above: possibly a hardware box from Telco is placed at both ends.
So can I safely say IPsec with above 1024bits encryptions is the secure choice?
Came across hardware encryption where a hardware module is inserted into
cisco routers at both ends but we are not doing this, then will it be software
encryption by firewalls then?

A Telco and VPN are not related. Are you asking for minimum security requirements for using SIP for VoIP?
Re Q3, a VPN tunnel is from one device to the other. Both devices have to perform encryption and decryption of the payload. Since a router usually just routes, and a firewall is for security, I would say the firewall does the work.
