Conclusions

iPECS LIK supports Skype Connect and the following was tested.

  • OK: In/outbound call with CPN.
  • OK: External forwarding (thru PBX, recursive).
  • NOK: External forwarding (302 Moved Temporary). (Is it supported by Skype?)
  • OK: Speed dials, Missed calls
  • OK: Removing country and/or area code from CPN.
  • OK: Dialing without country and/or area code.
  • NOK: CLIR. (Is it supported by Skype?)
  • OK: In/outbound call to MEX.
  • NOK: Sending original CPN to MEX. (Is it supported by Skype?)

Other issues

  • Skype is not using QoS and I did experience delay and bad sound quality in some situation. Skype is a service to provide low call rates and will not replace your normal provider.
  • The delay from you setup a call until the station in the far end starts to ring is also substantial. It often take around 10 seconds.

    We have followed your instructions but we are getting “Terminated” status on SIP User ID Index and the co line says “idle” any advice?
