Forwarding Calls from Skype to PBX RRS feed

  • Question

  • Hi all

    i have Skype for Business 2015 on premises and sip trunk

    I need to forward external skype calls to our sip trunk

    I have created Lync Account and set forwarding option to internal number

    When i call to this lync account from lync - forwarding works good

    if i call from external Skype - forwarding to pbx doesnt work

    logs:

    SIP/2.0 503 Service Unavailable

    reason="An internal exception received while processing the incoming request";component="MediationServer";Exception="An internal media error occurred"

    What i doing wrong?

  • Hi Dimitrii,

    As I understand, you use a SIP trunk to forward the call?

    You should analyze the SIP information form the mediation server and the SIP trunk. I think sip signaling has a problem with transfer (reffered-by, history info) because SFB did not use call div hinfo.
