Which codec does Nextiva use?

At this time, Nextiva’s only supported codec is G711U.

One of Nextiva’s goals is to provide the highest quality service in the industry. The codec does require more bandwidth than some other codecs, but we are intent on providing the best call quality possible.

If any other codec setting is used with Nextiva it will result in poor call quality or call failures.

Can I use an auto dialer with Nextiva SIP trunk sevice?

Note: Please keep in mind PBXs are managed by a resource at your company. Nextiva’s SIP trunk service is simply the means to establish a SIP connection for making and receiving calls. Beyond providing the SIP details and offering support on the initial authentication details, all other settings and troubleshooting is managed by your company’s IT resource.

Nextiva’s service allows auto dialer systems as long as the calls are for legitimate purposes and the ratio of calls does not exceed 1 call per 1 second. If your PBX or auto dialer software has a ratio setting, you will need to tune it so that no more than one call per second is dialing. Anything beyond a 1 call to 1 second ratio will result in call failure. Please note, although we allow auto dialers to be used, we aren't able to troubleshoot third party devices/software.

At this time Nextiva can only support this ratio, for not only our security but most importantly, our customers. Please see your PBX manual or your in-house IT technician for the steps to adjust calls to the Nextiva supported ratio.
