-------------------------------------------

Hi Alexander,

H323 faststart is unfortunately not a configurable item on Polycom RMX side.

Please find attached a new full trace:

10.44.1.156 = SIP client
10.100.202.88 = Asterisk server
10.71.0.55 = Polycom CMA
10.71.0.51 = Polycom RMX


Kind Regards

Gabriele Odone

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Addons/chan_ooh323
>    Affects Versions: 11.4.0, 11.6.0, 12.0.0-beta1
>         Environment: RH 5.5
>            Reporter: Gabriele Odone
>         Attachments: failure.pcap, PolycomRMX.pcap, success.pcap

>
> Environment:
> - Asterisk 11.4
> - H323 trunk between Asterisk and "Polycom CMA" (H323 Gatekeeper) using
> ooh323c module.
> - An H323 MCU  ("Polycom RMX") is registered to "Polycom CMA" gatekeeper.
> When H323 calls are placed by Polycom RMX, the following lines are written
> in /var/log/asterisk/h323_log:
> =========================
> 16:42:04:417  Asn1Error: -2 at ooh323c/src/decode.c:67
> 16:42:04:418  Error decoding H245 message (incoming, ooh323c_2)
> =========================
> The same code generating this error is also in the latest 11.6 and 12.0
> beta.
> Symptom: From the "Polycom RMX" side, the call is heard ringing. From the
> SIP side, the call is received and answered. See attached tcpdump example: failure.pcap
> If, instead of placing the call from the "Polycom RMX", I place the call
> from another H323 endpoint (registered to the same H323 Gatekeeper,
> "Polycom CMA"), the call goes through without such error (example: success.pcap).
> I suppose it is a H245 parsing error.
> In the attached tcpdumps:
> 10.44.1.60 = SIP client
> 10.100.202.88 = Asterisk server
> 10.71.0.55 = H323 Gatekeeper (Polycom CMA)
> 10.71.0.51 = H323 "client" (Polycom RMX) registered to H323 gatekeeper
> 10.44.1.156 = H323 client (Polycom CMA Desktop) registered to H323 gatekeeper
