| Description: | We're using IAX2 to establish a trunk connection between our proprietary system and an Asterisk server. However since Asterisk version 1.4.21.2, which fixed the "IAX POKE resource exhaustion" (AST-2008-10), we're having troubles using POKE requests. I am aware that the fixes incorporated in 1.4.21.2 include a change in the call number usage for POKE requests (call number 1). However when sending a POKE from our system to the Asterisk server with destination caller ID 0 we do get a PONG in return from caller ID 1. The problem is that Asterisk does not increase the Inbound Stream Sequence Number from 0 to 1 when responding with a PONG. As a result we run into a timeout after three unsuccessful tries. An ACK would be sent by our system only if the ISeqNo is also increased to 1 in the PONG. The same issue remains for 1.6.x so far. This clearly is not conforming to the IAX2 standard (draft). ****** ADDITIONAL INFORMATION ****** Tried with the following versions: 1.4.21.2 1.4.22 1.6.0 1.6.0.1 | ||
