[Asterisk-Users] Stun & codec
You can use Ethereal to see what your phone (stun) is sending. Of this way you can see the RTP ports and IP public that your phones are going to use. You can see that information in INVITE and OK packets. For other hand, If you use one router with symmetrical NAT then Stun won't work http://www.networkmagazine.com/shared/article/showArticle.jhtml?articleId=17602009&classroom= __ Renovamos el Correo Yahoo!

Thanks tony, why are the idle channels restarted?, the PSTN could think that my box has some problem. Perhaps, other equipments also make the same but I don't know anything about it. I used Access Server of Cisco and I think that the channels weren't restarted. __ Renovamos el Correo Yahoo!

[Asterisk-Users] E1 (Digium E100P) problem : B-channel succesfully restarted.
Hi! I have an Asterisk Box with one E1. This is connected with PSTN. My problem is that periodically the Asterisk console shows the following message. -- B-channel 0/1 succesfully restarted on span 1 -- B-channel 0/2 succesfully restarted on span 1 -- B-channel 0/3 succesfully restarted on span 1 -- B-channel 0/4 succesfully restarted on span 1 -- B-channel 0/5 succesfully restarted on span 1 -- B-channel 0/6 succesfully restarted on span 1 -- B-channel 0/7 succesfully restarted on span 1 -- B-channel 0/8 succesfully restarted on span 1 -- B-channel 0/9 succesfully restarted on span 1 -- B-channel 0/10 succesfully restarted on span 1 -- B-channel 0/11 succesfully restarted on span 1 -- B-channel 0/12 succesfully restarted on span 1 -- B-channel 0/13 succesfully restarted on span 1 -- B-channel 0/14 succesfully restarted on span 1 -- B-channel 0/15 succesfully restarted on span 1 -- B-channel 0/16 succesfully restarted on span 1 -- B-channel 0/17 succesfully restarted on span 1 -- B-channel 0/18 succesfully restarted on span 1 -- B-channel 0/19 succesfully restarted on span 1 -- B-channel 0/20 succesfully restarted on span 1 -- B-channel 0/21 succesfully restarted on span 1 -- B-channel 0/22 succesfully restarted on span 1 -- B-channel 0/23 succesfully restarted on span 1 -- B-channel 0/24 succesfully restarted on span 1 -- B-channel 0/25 succesfully restarted on span 1 -- B-channel 0/26 succesfully restarted on span 1 -- B-channel 0/27 succesfully restarted on span 1 -- B-channel 0/28 succesfully restarted on span 1 -- B-channel 0/29 succesfully restarted on span 1 -- B-channel 0/30 succesfully restarted on span 1 -- B-channel 0/31 succesfully restarted on span 1 I have look for in the source code to check the meaning of this message but I haven't found anything. The only thing that I could check, It's that T203=10 seg and T200=1 seg. For example, Cisco has T203=30 seg. In http://www.acacia-net.com/wwwcla/protocol/q921.htm I read the meaning of those timers. Could Asterisk restart E1 because It don't recieve anything before T203 finished? My configuration is: /etc/zaptel.conf span=1,1,0,ccs,hdb3 bchan=1-15,17-31 dchan=16 I don't know if this behavior is correct. Can someone help me?

[Asterisk-Users] Asterisk and T.38.
Hi Rafa! >Hi Jairo, > >Try with other values for the jitter in your Gateway (H323). > >One customer have a scenario like this: >Phone/Fax <> Gateways H323 -with 16/8/2/1 Port FXS- <---> GNUGK <---> Asterisk <---> Zap (E1) We have the same configuration, and I think that our problem is the jitter in Asterisk, since we have jitterMin=0ms and jitterMax=0ms. We changed chan_oh323.c because it didn't accept jitter less than 20ms (We used Asterisk to translate SIP --> H323-->Cisco, and the Cisco have jitter buffer, so we didn't need jitter buffer in Asterisk). Now, we have put: oh323.conf ---> jitterMin=20ms jitterMax=20ms codec=G711A frames=20 zapata.conf ---> jitterbuffers=20ms but fax still doesn't work. Anyideas? Other question. If Asterisk hasn't T.38 then Fax will need 64Kbps (G711)+ 16Kbps (IP+UDP+RTP) bandwidth, and that is much bandwidth. Is this correct?, Do you know any comercial implementation of T.38 to Asterisk?

[Asterisk-Users] Asterisk and T.38.
Hi! I want to send fax to PSTN with Asterisk, but by now I can't. I am using the following boxs: Internet Zap E1 Phone/Fax<> Gateway(H323)<---> Asterisk<---> PSTN The gateway H323 has T38 and T30. Before I began with Asterisk, I used Cisco to connect with PSTN, and the Fax worked very well in T38 (T30 didn't work, I think the reason is the jitter). I have read that Asterisk doesn't support T.38, is this correct?, is there any comercial implementation in Asterisk?. If Asterisk doesn't support T.38, how can I use it to send fax to PSTN? Thanks in advance. __ Renovamos el Correo Yahoo!: ¡250 MB GRATIS!
