We have a working ip trunk between astersisk and avaya. Now everybody tests asterisk with SIP and reports 100’s and thousands of calls.
But in our case, we tried a different setting. We fire some SIP/ISDN calls to asterisk, dial the IP trunk internally and play some sweet music on Avaya. But to our utter surprise, only 1 call is sent on the trunk
But if, instead of firing simutaneous calls from a generator, we try a manual one, say 6 people calling the extension and then reach avaya, all of 6 are handled concurrently.
I use ooh323, and we have enough licenses for avaya to handle 300 or 400 h.323 calls. What is limiting the asterisk to send concurrent calls on IP trunk, when it does send a delayed call(a call hitting the extension with a delay of 1 s than prev one)??
