IP Phones Unable to keep connection with ASA 5505

mpadderatz
Level 1
Level 1

Today we updated our ASA 5505 from ASA 6.5xx to ASA 9.24, and as we know around 8.1 the way NAT was done was changed. I was under the impression that the ASA would "convert" most of the rules, and I figured I would have to recreate some of them that failed.  Well, I recreated what I could but I still could not get the phones to work. Some preface of our network in question: 

Internet<-------ISP ROUTER<-----ASA 5505<-----SG-3000

  • Phones are a Ploycom VTX 400/410
  • The phones receive DHCP from the ASA, and we have a VPN tunnel created to our host for the phones. 
  • The phones are then come back from our branch office back into the main office via another VPN tunnel to go out 
  • The phones receive their option 60 from our hosted provider
  • The computers work fine and have no issue what so ever. The computers and the phones share the same IP range of the subnet.

The phones are getting everything correctly, IP, VLAN, DHCP, DNS, and configuration. The tunnel is established to both the main office and the hosted phone provider. There is traffic passing through both tunnels, and they are active. When I try to make a call from the phone it rings, connects, and then within 4 seconds, it hangs up with no voice being exchanged.

I inherited this network from a MSP that had provided IT to my company I work at for the last 4 years. They are to say, very reluctant to give information about the setup. Also, they provided no documentation what so ever, so here I am trying to figure this out. My config for my ASA is below, any help would be good or some information as to what to look at. I am quite a novice when it comes to firewalls, and this one would be the first one I would have configured albeit unsuccessfully.

ASA Version 9.1(7)11

I would initially try the following

Policy-map global-policy

class global-class

no inspect h323 h225

no inspect rstp

no inspect sip

no inspect h323 ras

no inspect skinny

I will give it a try Monday when I get into the office.
