Since your last question has been addressed by Pascal, I will attempt to answer the first three. Please keep in mind that, the Internet topology (location) of the users and the telephony providers do play a role in the call quality.
Zitat: |
Is the call quality affected in any negative way buy it passing through PBXes? |
|
That depends mostly on the provider (vocoder used) and the quality of the firewalls which are in front of your SIP endpoints. In general the voice quality is not affected or can even be improved through the PBX.
Zitat: |
Will there be an increase in latency - perhaps because of the extra routing through the PBX? |
|
In general, if the provider supports Re-Invites, then only the signaling will go through the PBX. The voice packets should go either between the SIP endpoints or between the SIP endpoint and the PSTN gateway at the remote end.
Zitat: |
If I receive a call on my extension and wish to pass it onto another extension will the call quality drop, will there be delays or echo? |
|
If only the signaling goes through the PBX then the voice quality should not be affected. A Re-Invite should direct the voice packets to the new SIP endpoint.
Zitat: |
My real question is the service reliable enough and of good enough quality to be used for the main line into our company? |
|
To help you answer your last question, I can tell you the following. The only way to find out if the PBX is the right solution, to be used as the main line into your company, is to try it. There is no commitment to get a free account, and the Premium account fee is on a monthly basis.
So set up an incoming number, a couple of extensions, and ask a couple of friends to call you. They will be the best judges, especially if you don't tell them it is VoIP based system. Blind tests are the best.
As your confidence builds, add more trunks and extensions. Within two months you will know if you have a winner, or you have to move on to another solution.
PS. If you need more in-depth explanation or help with the setup send me a PM.
