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

Hello,

>From first view there is error of decoding second TCS from called side after empty TCS that mean reestablish TCS&MSD exchange.
Decode error found on proccessing g729AB cap:

                    Item 5
                        CapabilityTableEntry
                            capabilityTableEntryNumber: 6
                            capability: receiveAudioCapability (4)
                                receiveAudioCapability: g729AnnexAwAnnexB (15)
                                    g729AnnexAwAnnexB: 2

Its interesting that same cap was decoded without errors from fist TCS.

Could you disable g729 codec at answered side for test?

> OOH323 isn't responding to TCS from remote end.  Lack of TCS AWK from Asterisk results in TCS timeout (standard timeout of 5 seconds) and the clearing of the call.
