I downloaded the technical sheet of the Harris TM604G/CT I have for telephone service to see the codecs capability. Does anyone know what codec is in use in this telephone service service?
I ask because the Cisco DPC3939B gateway I must use in order to have telephone service thru comcast is hardly configurable, there is a Public WIFI that currently only technicians can turn off and it switches back on at will, reducing bandwith and degrading telephone sound. I wondered if the Harris equipment would speak ILBC which is a free and low bandwith codec.
Is there a choice to the Harris TM604G/CT I see is DOCSIS 2.0 and 3.1 is due this year.
Codec: G.711, 64 kbps, μ and A-law encoded speech;
Enhanced codec firmware support (G.726, G.728, G.729E);
T.38 Fax Relay;
DOCSIS 2.0 based;
PacketCable 1.0 & 1.5 based;
RFC3261 SIP: Session Initiation Protocol;
UL® 60950, FCC Part 15 Class B, CE
Is it posible to connect instead an Asterisk server, which has all those codecs and ILBC, would Comcast speak ILBC? would Comcast speak to an Asterisk server instead of the Harris?
thank you for your interest and comments
