...As my application is the CA of Stretto 2000, everything it sends (RSIPs, acks, etc.) my app answers. And everything I send, Stretto answers. At extensions.conf (Asterisk) I have the following number of my softphone in another PC: exten => 123456,1,Dial(MGCP/aaln/1@leonardo) When my app sends CRCX to Stretto, it answers with a "200 <transaction_id> OK, with session description", but the channel on the E1 card is not occuped and the softphone doesn't ring. I was observing the Asterisk debug screen, but nothing happens. It seems the connection doesn't leave the Stretto...

Sirs, I have a question about CreateConnection (CRCX) at MGCP. For example, I have the phone number "5220107" and want to make a call for it using MGCP through a media gateway. How can I proceed? I know the command I must send to the media gateway should be like this: CRCX <trans_id> <endpoint> MGCP 1.0 "C", "L&q...

...e criteria to the generation of the transaction identifiers in MGCP? I mean, are they generated by a randomic method? I'm using Asterisk and MGCP eyeP Phone and observed that the RSIP and NTFY (methods created by the gateway) use high values in the transaction identifiers, while the RQNT, AUEP, CRCX and DLCX (by the call agent) use low values for it. I hope I could explain my doubt! Here are some examples: RSIP 18696 aaln/1@tramontina MGCP 1.0 RQNT 8 aaln/1@tramontina MGCP 1.0 AUEP 9 aaln/1@tramontina MGCP 1.0 RSIP 27232 aaln/1@tramontina MGCP 1.0 RQNT 3 aaln/1@tramontina MGCP 1.0 NTFY 27219...

We are using an MGCP configuration. There seems to be some incompatibilities between our Netergy T2 VOIP chip and Asterisk. This is how our Vendor sees it: Here's what I see. 1. The first call is initiated. (CRCX) The interesting thing here is that the CA (Call Agent) tells us to go directly into sendrecv mode which means that we start streaming audio immediately. All other CAs that we've worked with do not instruct us to go to sendrecv mode until the number has been completely dialed. 2. The call i...

Hi. I'm new in Asterisk with MGCP. I set up a MGCP user agent and start asterisk with the next configuration files. '--------------- extensions.conf ---------------------------------------------------- [general] static=yes writeprotect=yes [globals] ap1 => mgcp/aaln/ap200@64.76.148.186 [macro-apl1] exten => s,1,Dial(${ARG1},30,Ttmr) ;exten => s,2,Voicemail(u${MACRO_EXTEN})

...except that audio is one way (from 5300 to MGCP gateway only). It seems that during reinvite Cisco gets confused by session ID and version and excpects RTP stream on different port. The call flow on SDP level is following (ports and id's are pure fantasy for easier reading): * -> MGCP CRCX (session 1, port 3001, destination *) * -> 5300 INVITE (session 1, port 3002, destination *) 5300 -> * OK (session 2, port 4001, destination 5300) (ring and answer, * tries to bridge the call legs) * -> MGCP MDCX (session 1, port 4001, destination 5300) * -> 5300...
