[asterisk-users] SPA2100 sends an unexpected BYE message when transmitting a FAX
Hi everyone, I'm trying to send a FAX with the following configuration: Analog FAX machine (OKI) <----->SPA21000<----->LAN<----->Asterisk<--------> PSTN I'm restricted to use passthru mode for faxing, instead of T.38 protocol, because the Asterisk box is running v1.2 and cannot be changed as it is in a heavy production environment. Anyway, it "should" work in passthru mode (G.711a) as the ATA and the Asterisk are in the same LAN with very low traffic. The problem arises when I try to send a fax: the Asterisk server initiates the call and, after a few seconds, the Linksys hangs the call by sending a BYE message: DEBUG[7416]: chan_sip.c:11375 handle_request: **** Received ACK (6) - Command in SIP ACK DEBUG[7416]: chan_sip.c:1396 __sip_ack: ** SIP TIMER: Cancelling retransmit of packet (reply received) Retransid #258 DEBUG[7416]: chan_sip.c:1407 __sip_ack: Stopping retransmission on 'e793a727-98582c99@192.168.6.222' of Response 102: Match Found <-- SIP read from 192.168.6.222:5060: BYE sip:9021111111@192.168.6.220 SIP/2.0 Via: SIP/2.0/UDP 192.168.6.222:5060;branch=z9hG4bK-6b0d80f5 From: 201 <sip:201@192.168.6.220>;tag=c6bf15cfef0f4e11o0 To: <sip:9021111111@192.168.6.220>;tag=as715a2601 Call-ID: e793a727-98582c99@192.168.6.222 CSeq: 103 BYE Max-Forwards: 70 Proxy-Authorization: Digest username="201",realm="asterisk",nonce="36741c67",uri="sip:9021111111@192.168.6.220",algorithm=MD5,response="94f0139b69bb01ddc4aa362ab3edc130" User-Agent: Linksys/SPA2100-3.3.6 I'm using the following features: - Network jitter buffer: very high - Jitter buffer adjustment: disable - Call Waiting: no - 3 Way Calling: no - Echo Canceller: no - Silence suppression: no - Preferred Codec: G711a - Use pref. codec only: yes - Silence Threshold = medium - Echo Canc Enable = no - Echo Canc Adapt Enable = no - Echo Supp Enable = no - FAX CED Detect Enable = no - FAX CNG Detect Enable = no - FAX Passthru Codec = G711a - FAX Passthru Method = NSE - FAX Process NSE = yes - FAX Disable ECAN = no - FAX Codec Symmetric = yes - DTMF Tx Method = auto - Hook Flash Tx Method = none - Release Unused Codec = yes I have checked the SPA2100's logs, but I can't see anything of interest (and I couldn't find any documentation about this logs at Sipura's website). Has anyone suceed in sending a fax in a scenario like this? I would appreciate any help on this point. Best regards,
