[Asterisk-Users] codec negotiation with CISCO 7960 and Firefly softphone
Hi all, When I am making call with with my Cisco 7960 SIP phone, I found only codec g711 works. The network call is like this: CISCO AS5300 ---sip----> Asterisk ----sip---> CISCO7960 Peer User/ANR Call ID Seq (Tx/Rx) Format cisco7960 30511694 152828207b0 00102/00000 ulaw ciscoAS5300 34169980 31A6EE0B-AF 00101/00101 gsm Codec in CISCO AS5300 g711alaw G.711 A Law 64000 bps g711ulaw G.711 u Law 64000 bps g723ar53 G.723.1 ANNEX-A 5300 bps g723ar63 G.723.1 ANNEX-A 6300 bps g723r53 G.723.1 5300 bps g723r63 G.723.1 6300 bps g729br8 G.729 ANNEX-B 8000 bps g729r8 G.729 8000 bps gsmefr GSMEFR 12200 bps gsmfr GSMFR 13200 bps I already did the following config in sip.conf allow=g723 allow=g729 allow=gsm allow=ulaw allow=alaw However, it seems that only codec gsm work fines. However, it still occupy more bandwidth. Just would like to know if asterisk can do codec g723 or g729? Anyone has encountered this problem or am I missing any config in asterisk? Thanks.
