Hi,
My setup include one freepbx(freepbx-1) with single NIC.
Background:
The NIC has bind to a private IP : 192.168.1.10/24 with default gateway 192.168.1.1 which is a Cisco ASA doing NAT to SIP provider. All IP phone is on 192.168.25.0 network.
The SIP provider assign an IP address : a.b.c.d. for freepbx-1 to connect to their SIP server w.x.y.z. I must use this IP a.b.c.d to get connection to SIP server w.x.y.z because SIP provider will base on source IP a.b.c.d to accept the CID freepbx-1 send out. This SIP circuit provide 100 public phone number(CID-1) to use.
Current status:
All public phone number is used and I have request another set of 100 public phone number(CID-2). The SIP provider has assign second set of IP address e.f.g.h for freepbx-1 to connect to the same SIP server w.x.y.z for using the additional 100 public phone number(CID-2).
Problem:
My problem is I can only setup one static route on ASA to the SIP server w.x.y.z via a.b.c.d or e.f.g.h. If I setup via a.b.c.d than SIP server won’t accept CID-2. If I setup via e.f.g.h than SIP server won’t accept CID-1. So I can’t setup 2 static route to the same destination and SIP Provider only has 1 SIP server to use.
Question:
- Is it possible to setup multiple NIC in freepbx for difference SIP circuit?
- How to setup freepbx to pick the correct NIC to use base on CID not IP routing?
- Or should I setup a new freepbx server(freepbx-2) for new SIP circuit and route the call from freepbx-1 to freepbx-2?
Thanks.
