## Questions & Answers

**Q: Can you use this phone for voip intercom between several offices?**
A: There are a few ways to implement this.  (1) The simplest is to use sub-accounts with your SIP service provider.  Callcentric, for example, supports 21 sub-accounts with extension numbers 100 to 120, so you register one phone with x100 another with x101, etc. and dial 3-digit extensions to make calls without hitting the PSTN or having any per-minute charges.  Voip.ms can also do this.  (2) For larger deployments you may want to consider using a PC running Asterix/Freeswitch or a PBX appliance to provide your own SIP service.  (3) If you don't want to mess with a SIP provider and a self-hosted PBX is overkill, this device, like most Grandstream products, supports "direct IP call" where you dial the network IP address instead of a phone number.  With this method you don't even need an internet connection if the phones are on the same subnet, so you can, for example, stick a phone in the back warehouse and call it from the front office.

**Q: Can these phones work with Asterisk? Thanks**
A: Yes, it works with asterisk (confirmed with asterisk 1.8).

**Q: Does this item include a power cable for networks that don't support PoE**
A: No, 1620 is not PoE.  You may consider 1625 or 2130 for PoE

**Q: Does it work with Skype?**
A: no

I've been using CISCO IP phones for more than 15 years in my office and got absolutely no problem with them. But Grandstream at this pricing was a much cheaper option. I found the Grandstream phone to be much sleek and as efficient. It was much much more easier to configure as compared to Cisco. We have decided to slowly replace all our phones with this brand. Even the seller was very supportive.
