What do you mean? Am I able to modify and compile the source? Is it compicated? (I'm not a developer) Based on the SDP in your gist the remote implementation has given no attributes with the T.38 stream which makes it pretty broken (T38FaxRateManagement is mandatory) and fun. The two hard parts really would be 1. Modifying Asterisk in a sane fashion to cope and 2. Determining the exact settings to make the implementation happy. Defaults as defined in the spec are fine and good, but my experience has taught me to throw those out the window when it comes to actual implementations. It would seem that having a configurable option would be an idea for this scenario. That implies it would solve the problem, which my gut and experience tells me... it wouldn't. I think the T.38 implementation is just cobbled together and without knowing exactly how it behaves getting it to work would likely be a nightmare (trust me, I've spent time in those deep dark reaches). Throwing assumptions and defaults at it to try to make it work is of course an option. My testing with Asterisk 1.8 and T.38, I obserevd that setting FAXOPT(minrate) or FAXOPT(maxrate)had no effect, I concluded that when Astrerisk is receiving it uses hard coded values - is this a sane thing to do?! When Asterisk is receiving the stack implementation offers what it wants, with the ability to override. So Asterisk doesn't hard code those values, the stack provides them. What is hard coded is the default values if none are received. I would even say it's a bug that the negotiation doesn't fail, since the remote side isn't providing a mandatory attribute. -- Joshua Colp Digium, Inc. | Senior Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com www.asterisk.org -- _ Yes you're right! As I know FAXOPT() value affect only when asterisk woks as gateway. We need passtrouh because my endpoints and also my provider supports T38. https://wiki.asterisk.org/wiki/display/AST/T.38+Fax+Gateway Using T.38 Gateway mode T.38 Gateway mode should be used when one leg of a call is not capable of T.38 mode. In the event that both legs are capable and Gateway mode is configured, then the Gateway will step out of the way, allowing transparent T.38 passthrough. The main problem is that I can't use G711 for the entire fax session because the endpoints has 20-30ms response time. When I try to use my Asterisk as FAXOPT gateway (endpoint leg T38 and provider leg G711) can I force somehow to not accept the T38 re-INVITEs from the provider? They have ~1ms response time, so G711 on that leg would be fine but they also detect fax CED tones and sends the re-INVITEs. Have you tried setting in your sip.conf for your provider t38pt_udptl=no whilst having the gateway option enabled? Sorry I cant test this myself.

Re: [asterisk-users] Queues: Knowing when a caller is position 1 (agent phone ringing)
Hi,
Our queue members are Local channels, thus when dialing the agent, the
dialplan will do several stuff including:
Set(CALLERID(name)=${CALLERID(name)}:Sales)
UserEvent(something,data: ${bunch-of-data-in-some-format})
Dial(SIP/final-agent-phone,timeout,A(Sales))
The UserEvent will be picked up by our client-register-ticket-stuff software
The announcement A() will be heard by the agent upon answering the call
like sales call

Re: [asterisk-users] Queues: Knowing when a caller is position 1 (agent phone ringing)
Dear Mitch, Thank you so much. This partly solves my problem by a great deal, as we'll send a message to the agent immediately on picking the call. As the agents are local SIP channels, I will attempt looking up the caller's name (if it exists in our database) and set it prior to entering the queue. Is there any way of informing the agent (just) before they pick up? e.g when their phone starts ringing, so that they prepare accordingly?

Re: [asterisk-users] Queues: Knowing when a caller is position 1 (agent phone ringing)
Dear Tiago,
Thanks for your answer, but I have a few questions.
Do you use queues? We are operating a call centre with several queues,
so I don't see how we would use the Dial command. When a call comes
in, we enter the caller (depending on what options he has selected)
into a queue. Do you have any alternative method, which would involve
dialling the agent directly as you described below?
regards,
T

Re: [asterisk-users] Queues: Knowing when a caller is position 1 (agent phone ringing)
Hi,
You just said you use Local channels. Local channel is a dialplan that has
a Dial() to a sip device?
We use queues, and have a queue-macro that sends the UserEvent upon
bridging the call...
