Hello all,
I came a cross a problem yesterday that I don't quite know how to solve. I am trying to use * to connect to net2phone, and have a net2phone MAX IP-10 connect to net2phone. From the settings on http://www.voip-info.org/ it was easy to get asterisk to connect to the network - acting like a net2phone device/user. Anyway the problem arose when attempting to call the MAX IP-10 device through the net2phone network. They seem to be using the G732.1 codec. I have in my settings in sip.conf allow=G732.1 or what ever flavour of the like and still I can not talk to the two devices. I googled a bit and came across the fact of * being able to do a pass through - well I was not successful and this subject is either simple or not well documented. The devices are using SIP and there is a bridge initiated, but there is no audio and no voice being passed through... I have tried connecting as the receiving device a GrandStrem Budge Tone-100 and still no luck. So all that I am inquiring is has anyone successfully done a pass through and if so can someone please guide me through some of the settings. I have set the [net2phone] with a canreinvite=yes - that a post on a forum also suggested, and that also did not work.
On a separate issue: When the Grandstream Budge Tone-100 is connected on the internal network then the audio and the voice in both directions work fine. But when the device is connected on a separate network - ie on an other ADSL line, then the device doesn't send voice packets although is receives packets. I have opened up IPTABLES, to allow udp 5060 and udp 10000:20000 in both directions on any interface and the problem still persists. (SIP phone: Grandstream Budge Tone 100 connects to * and the call is answered by a Softphone X-Lite with all the codecs enabled. As far as I can tell thy both are "speaking" with a G711 codec ULaw/ALaw).
So can anyone please give me a guideline or some advise on where to look to solve the problem.
-- Kind Regards Etienne
