CS1000E Release 5.5 to OCS R2 RRS feed

  • Question

  • Hi

    I have a CS1000E release 5.5 to OCS R1 using a MCM/PROXY SERVER and work well, and now I need to migrate OCS R1 to OCS R2, whit the same version on CS1000E.

    Whit OCS R2, I can make a call from MOC to the PSTN, but calls from PSTN to MOC and PBX extension to MOC are unsucessfull, in the SIP Trace the messages is SIP/2.0 488 Invalid incoming Gateway SDP: Gateway ParseSdpOffer Error: No DTMF support on Gateway side,

    I test whit configuration DIRECT SIP whit the same result.

    I use a Nortel´s bulletin for integration and install the patches in the CS1000E (Some patches that the bulletin says for CS1000E system, are changed for new versions). Anyone have and idea to resolve the problem???

    thanks in advance
