AS5300 with AS5350

Discussion in 'Cisco' started by Alexander Nazarenko, Jul 13, 2003.

  1. Our partner is using AS5350 and we have problem with g729r8 codec between
    these gateways.
    We use codec = g729r8, payload size = 20 bytes on both ends, but when
    AS5300 terminating calls I see calls with pre-ietf codec

    22E6 : 30114375hs.147859 +338 +357 pid:3 Answer xxxx
    dur 00:00:00 tx:0/0 rx:0/0 2C (no requested circuit.)
    IP x.x.x.x:18770 rtt:0ms pl:0/0ms lost:0/0/0 delay:0/0/0ms g729r8 pre-ietf

    About 30% of all calls come with right g729r8 codec (non pre-ietf) and
    AS5300 can successfully terminate them. But pre-eitf calls get "dsp error"
    on further dial-peers.

    1353 : 30163075hs.147862 +-1 +347 pid:9821 Originate xxxx
    dur 00:00:00 tx:0/0 rx:10/1600 AC (dsp error)
    IP x.x.x.x:18892 rtt:0ms pl:0/0ms lost:0/0/0 delay:0/0/0ms clear-channel
    (Call passes PSTN Loopback before reaching this dial-peer)


    I've read that AS5350 doesn't support real g729r8 and g729br8 high-complex
    codecs, but it supports only medium-complex g729 ones. Can this be the
    cause of problem?
