Hi,
I have quite a low bandwidth broadband connection at home and want to balance call quality with bandwidth usage.
I've seen the post that recommends GSM for low bandwidth applications, but my phone (Grandstream GXP2160) doesn't have this available.
What are the bandwidth and audio quality properties of each of the following available codecs?
PCMU
PCMA
G.722
G.726-32
G.729(A/B)
Many thanks,
Andrew

Hi Andrew,
The phone will be set to use PCMA by default and for a single call will use around 0.15 Mb/s of your broadband bandwidth, most residential broadband connections will provide more than enough bandwidth for a single call.
Grandstream no longer support the GSM codec on their new phone models.

Hi Robert,
Thanks for the reply.
The phone is actually set to use PCMU by default.
I have two phones running at home and there would potentially be more than two lines in use if a conference call is set up.
Also, even with a single call in progress if I try to do something else that is bandwidth-intensive (such as download a Google map) the VoIP call starts breaking up.
After a bit of research it looks like G.729 might be the best option.
Thoughts?
Andrew

Andrew,
We can enable G729 on your account if required (it is not enabled by default), however, would you be able to post results of tests ran at
pingtest.net
and
speedtest.net
so that we confirm that this would be the best solution? It may be easier if you send the result in an email to
support@soho66.co.uk
so that we can advise further.
