[Asterisk-Users] codecs question ..

[Dave Alan Caruana]

My system is an asterisk machine,
with an E1 card (functioning) and
forwarding calls to a remote SIP
address ..

when a call connects I am getting the
following error :

NOTICE[1240577216]: File rtp.c, Line 330 (ast_rtp_read): Unknown RTP codec
19 received


can anybody tell me what this means
(& how I may fix it ?)

cheers
Dave

ps. the service i'm connecting to uses G723
