Hi there I recently installed a UC520 in my office for testing and I have a problem that when calling from outside (My mobile for example) the phone shows (From Unknown number) message I checked an article talking about the same problem but it did not work for me, so I'm wondering if there is any caller-Id option need to be modified.
My UC520 is intalled in KSA with STC service provider and the caller-ID service is working (tested by a normal phone) and here is the configuration that I have for the voice-port:
connection plar opx 202
description Configured by CCA 4FXO-0/1/1-Custom
can you help me with that ?
We have seen in the past that some providers in Saudi Arabia don't use Bellcore standard for CLID (which is what "cptone SA" invokes). Go ahead and use another profile, "cptone BR" for Brazil and don't forget to do a "shut", "no shut" of the voice port.
Let us know how that works.
