TN1: Configuring a SPA504g for use with IP-Phone-C
Subscriber Information
Configure an extension as follows:
EXT > Display Name = <Phone Number> EXT > User Id = <Phone Number> EXT > Password = <Password> EXT > Use Auth Id = Yes EXT > Auth Id = <User Id>
Audio Configuration
The IP-Phone-C SIP server only supports the G711u codec. Other codecs, or too many proposed codecs, may trigger a "488 Not Acceptable Here" response. Therefore configuration with just G711u is recommended.
Configure an extension as follows:
EXT > Preferred Codec = G711u EXT > Use Pref Codec Only = Yes
RTP Packet Size
The IP-Phone-C SIP server only accepts a SDP attribute a=ptime with the value 20. Any other value will result in a "488 Not Acceptable Here" response, incorporating a "307 Session description parameter not understood" warning. The engineer who programmed this is a bad person.
The SPA504g emits the correct value with the following configuration:
SIP > RTP Packet Size = 0.02
