I don't think it is, but I wanted opinions. I was asked to look at flowroute for a potential deployment. After monkeying around with their portal, which has its own quirks, I saw the following behavior...
Invite from FR on port 5080 at their ip 216.x.y.z, then I saw the call fail to setup (BYE) from sipx due to no response (timeout) from the other side. In my case this is a dual wan and I routed FR's network via a dedicated connection on the router. Works for Appiaservices, voip.ms, bandwidth.com, etc., so all is without issue "except" for flowroute. After doing another test call and getting a pcap from the firewall, I noticed the RTP was being sent by a foreign (Level 3) IP address 4.a.b.c. My question: If the signalling for the call is established with one IP address, does a totally different IP address for media break any rules? I'm guessing not because the call worked once I routed the level 3 address(s) via the other wan connection. While I don't think it's particularly good behavior, is there anything improper other than an ACL or routing rats nest that this tye of ITSP routing introduces? -- ====================== Tony Graziano, Manager Telephone: 434.984.8430 sip: [email protected] Fax: 434.465.6833 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 sip: [email protected] Helpdesk Contract Customers: http://support.myitdepartment.net <http://support.myitdepartment.net>Blog: http://blog.myitdepartment.net Linked-In Profile: http://www.linkedin.com/pub/tony-graziano/14/4a6/7a4 Ask about our Internet Fax services!
