Hi,
Would it be ok if we set up SIP trunk for outgoing calls without a SBC for an IPO 500 V2 on 9.0.4 behind a firewall, assuming we make the following settings:
- Firewall access control only allow communications between ITSP SIP server IP and the public IP
- Port forward only 5060, 5061 and RTP port ranges
We'd really like to avoid the added cost of SBC without sacrificing too much security.
Thanks in advance!
