Hello all!
I have a setup with 2 SRX220's, in a clustered setup. They have about 25 IP phones/devices, connecting to Vonage Business (Vocalocity) over a dual WAN setup. I have filters, and NAT configued to put the VoIP traffic (separate vlan) on ISP1, which is about 80x60mbps, where I have standard/regular data using ISP2, which is a 100x100mbps connection.
All of a sudden, after a power cycle, VoIP is working horribly. They are gettting dropped calls and tons of one-way audio. SIP ALG is disabled, and I've recently also enabled UDP timeout of 180 seconds. Nothing is working. We had the voice traffic on ISP2 until yesterday, but the problem, which started Thursday, is still happening (coensiding with the power cycle).
Any ideas? I'd also like to get feedback on prioritization. I don't technically need it as my router has 2 ISP connections, and I'm using one for voice, and one for data, so I shouldn't have a contension issue, but I would like to make sure the voice is given every opportunity to survive.
I'm running 12.1X44-D20.3 on both SRX220's. Clustering is working, as is all other traffic inbound and outbound. I have several VPN's for remote sites, and client VPN's, and all is working seemingly correctly. The only thing that is strange, is that phone calls are having issues. This is a fairly high volume sales floor so calls are very important.
Anyway - please give your thoughts, and ideas!
Thanks in advance!
