Since a while I'm using a Grandstream HT-286 SIP-adapter. It's working fine, but it has the limitation that it only can handle 1 SIP-account. I'm using several SIP-accounts by several registrars (including local phonenumbers in different countries), but unfortunately the Grandstream equipment can only handle 1 SIP account. For example, the AVM Fritz!Box Fon (can handle up to 10 different SIP accounts simultaneous. I know that there are services like SipSnip.de, which can 'bundle' SIP-accounts, but when the SipSnip server is down, all SIP-accounts are off-line. It's ofcourse more secure to configure the SIP-accounts in your own equipment. When one service went down, the others are working fine. I would like to ask Grandstream owners, to drop a line at email@example.com and asking for adding this feature in the next firmware upgrade. Only if you need this feature ofcourse :-). It would be great if we could add +/- 5 SIP accounts to the Grandstream HT-286 / HT-486 hardware. Thanks in advance.
