Hi,  I have a DX650 phone which was working perfectly fine till last week. This phone is installed at a SRST site. All of a sudden, outgoing external calls from the DX650 stopped. I am able to make internal calls and am able to receive calls (internal and external). However, outgoing external calls are not working.  Below are the steps carried out from my end in order to understand the issue:  1. Changed the handset from a DX650 to a CP-7821 phone. Phone registered and incoming and outgoing calls (internal and external) calls are working perfectly fine.  2. Changed the CSS profile of the DX650 phone to other profiles (like receptionist, normal users). Phone registers but only incoming and outgoing (internal) are working. Outgoing (external) calls are not working. 3. Changed the CSS profile of the DX650 from the site to HO configuration and the DX650 phone registers and incoming and outgoing calls (internal and external) calls are working perfectly fine.  4. Changed the phone to another DX650 phone and with the same CSS profile. Same result as Point 2. Outgoing (external) calls are not working. Could you kindly explain what seems to be the issue and what needs to be done in order to correct this issue?  ... View more

Hi,  I have a client who is need to upgrade his telephone system from his existing UC560 telephone system to BE6000S since they are adding new users. I would like to understand if their current SPA502G and SPA525G2 phones would be compatible with BE6000S? If yes, are there any restrictions on features?  As per BE6000 documents, BE6000 supports SIP endpoints and to the best of my knowledge, the SPA502G and SPA525G2 phones are also SIP endpoints.  Kindly advise me on this case please.  Thanks. ...

One of my client's is pretty much convinced with the Cisco UC540 and Cisco UC560 telephone system. However, he needs confirmation whether the systems will support DISA (Direct Inward System Access)? Basically, he would install the 2 systems in two different countries... with this, a user from country A would call up the system in country B, and then use one of their trunk lines to make outgoing calls in country B. ...
