In all cases it's better to use any kind of VPN tunnel or a VLAN between sites. This should be your first priority. Using a tunnel will increase also security and in some cases will provide QoS -- depending on router(s). If applicable you may use 3CX tunnel (with 3CX softphones or 3CX proxy server). Nevertheless 3CX tunnel is not providing security, it solves most NAT/firewall issues.

Using STUN / NAT may be more complicated and not fully universal, as some routers use different NAT models and firewall may block specific ports / services (second priority).

Using MirkoTik routers like RB750GL is a good and inexpensive choice for connecting sites (supports many types of tunnels, incl. OpenVPN and IPsec and has many options, incl. support of BGP, MPLS, etc.)

Hope this answers your question, if I understood you correctly.

Tks for your reply.

do you have test 3cx Proxy server with v10 ? because in v9 some bugs exist, and services crash sometimes.

tks advance

I haven't noticed any problems with proxy server and Version 10 (I think the proxy server didn't changed).
I always prefer to use VPN tunnel between sites, not 3CX proxy server. There are several reasons for this:

- need for a PC to run it (sometimes this is an issue)
- no way to provide QoS (sometimes this may be very important)
- not possible to run 3CX MyPhone application
- no security (encryption) of tunnel (could be necessary / preferred)
- problems with some phone (Aastra)

Meanwhile I'm quite satisfied with MikroTik routers -- inexpensive (about € 50.-/$70. for RB750GL) and feature-rich, you can easily set various tunnels like pseudo-wire, GRE, PPTP, L2TP, IPsec, OpenVPN, etc., implement prioritization of VoIP traffic, load balancing, etc., even BGP, OSPF support. Normally you have this functionality in routers which are more than 10 times more expensive (Cisco, Juniper, Huawei).

- not possible to run 3CX MyPhone application

This is possible, however not through the SIP Proxy Manager. I connect to the MyPhone remotely all the time no problems.


Thanks,
