Grandstream HT488 with Asterisk?

Does anyone have any experience using the (relatively new) Grandstream HT488 for PSTN access with Asterisk?



It work as expected. That is, the PSTN number you should pass on your HT488 must match the whole PSTN number you have configured on your HT488 earlier. If you have configured your HT488 with PSTN prefix, passing a call through your * to HT488, the HT488 will gives you dialtone so you have oppurtunity to dial the complete PSTN number. Now this call will progress if and only if it match the prefix you have configured on your HT488. Without doing any configuration on your HT488 it doesn’t work. That’s my experienced.
