I have a 406 Processor with 4.2.4 software on it, and I am using SIP trunking. The 5610sw ip phones that I have sound great ext to ext, but if you talk to somebody externally the person on the IP phone hears a terrible quality, however the person externally hears the person on the IP phone just fine. All the digital phones have great quality as well, to eliminate the IP network, I plugged the IP phone directly into the LAN port on the IP office and same result. We are using G7.11 ULAW 64k, and I went into Extensions and changed the IP phones to that instead of Automatic Selection as well as checked/unchecked Allow Direct Media Path and messed with some other check boxes. Any suggestions would be appreciated.

It shouldnt make any difference as far as I know. They are both exactly the same in terms of hardware - the only difference is literally the number 1 or 2 lol

I have a question concerning MattKnights comment about putting an IP Phone on the SIP Lan. When I do that the phone won't ever come up being that the TFTP server is on the voicemail machine which is a local address, how can I make this work?

The phone will time out waiting for the TFTP server. after that it will register ok

Take Care

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.

you need to give it an appropriate IP address, mask, Router and Gatekeeper address (Gatekeeper & Router) = IP address of LAN2 of IP406

Take Care

Put the vm/tftp server ip address in the "Primary Trans. IP Adress" and enable NAT on LAN2. Then use the ip adress of LAN2 as the gatekeeper address for the IP Phones and use the ip address of the vm/tftp server as the fileserver ip address in the phones or move the vm server/tftp server to LAN2, or add a second NIC in the vm server and connect that to the LAN2, or add a router between LAN1 and LAN2 and use that as a gateway for the phones.

I appreciate everyones help on this topic, as I am still having the issue. I have been on the phone with Avaya for the past couple days and they agree that I have everything right and that their is a codec mismatch. The carrier is telling me that they have their stuff set on G.711 ULAW, and I have my stuff set on that as well, if I tell them to set their stuff to G.729, and then I set the IP office to the same, (just for a mere test) is their any downsides? Is G.729 simply worse quality? What is the difference that I am looking at.

Lower bit rate for quality 8kb of voice (total 35kb each way of traffic) where g711 uses 64kb for voice (same as isdn, total 95kb each way of traffic).

Most customers won't notice the difference.

The fourth post in this tread mentioned a list of supported Avaya SIP trunk providers. Can anyone point me to where I can find this list?

Thanks.

loss=256, you have a local network problem.
So check the network/switches/ipoffice

Just to let everyone know, I fixed the quality issue and it was indeed the carrier. Nuvox (our carrier) said that they talked with Advanced Services and they changed the packet service profile setting from "No Transcode" to "Nuvox Transcode", they said this was the first time they had done SIP Trunking with an Avaya phone system, and all their other customers have been set to "No Transcode", so if anyone ever uses Nuvox (at their own risk considering Avaya doesn't support it) make sure you tell them that. Thanx again everyone
