How to Set Up: U-Verse with Nextiva

Problems relating to SIP-ALG:

The U-Verse service requires the customer to use a router that was designed specifically for U-Verse Internet, TV, and phone service.  This router has a default setting called SIP-ALG that cannot be disabled and the router cannot be replaced while using U-Verse internet.  SIP-ALG is a router function that will cause Nextiva’s traffic to be rewritten, which can cause problems such as one way audio, dropped calls, and inbound and outbound call failure.

Nextiva is proactively prepared for this.  Our server will send traffic that avoids this disruptive SIP-ALG functionality, but the phones/devices connected to this network may need to be modified, as well.

If you are familiar with making changes to your voice over IP phone/device, you will want to modify the source port of the phone to a port other than 5060 and reboot the U-Verse router.  If you are not familiar with making this change, we encourage you to contact our support at 1(800) 285-7995 and request assistance.

Inability to use Quality of Service (Bandwidth Allocation):

Quality of Service (QoS) is a function within some routers that allows you to allocate bandwidth to specific devices as needed.  Since U-Verse requires the use of their routers, you are incapable of implementing a QoS capable router while using U-Verse Internet service.  If you are using U-Verse Internet, you will be required to monitor the bandwidth being used at the location.  If there is too much downloading/uploading on the network it could cause the phone quality to degrade.
