[asterisk-users] Asterisk Vs FreeSWITCH for Fax
Hi We are using Spandsp + FreeSWITCH for receiving Fax over T.30 E1/PRI and the results make us sad :( I suppose Asterisk also has the option of using spandsp or a commercial version from Commetrex. What are your experiences with receiving Fax on spandsp or commetrex on Asterisk ? Does it really matter whether I use Asterisk or FreeSWITCH ? regards, Anita -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] T.30 Fax and Echo Cancelation
Hi I know that all echo cancelers are supposed to shut down when they hear the CNG or CED fax tone. Is this always a good thing ? I know that T.30 is supposed to be half duplex, so echo should not be there but in my session recordings, I have seen both sides trying to send at the same time (is that a sign of some other bad thing?) What if my T.30 fax is failing due to echo ?

[asterisk-users] Combining multiple SIP providers
Hi What is the best way to combine multiple SIP providers to achieve 1) Higher concurrency (for eg. 2 providers with 50 concurrent calling limits could be combined to give a limit of 100) 2) Redundancy (use another if one is down) I have a feeling that this will need some SIP Proxy like OpenSIPS but what could be the architecture ? Much thanks! regards, Anita -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] fax tone testing
Hi I suspect that my telco set-up is acting funny and I want to use spectral analysis to confirm the culprit :) What is the best way to generate Fax tones from a dialplan and then record them at the other end? Also, where can I get a list of the all the tones and duration which are used in Fax.

[asterisk-users] Best Way to Send Fax on Sangoma ?
Hi What should be the optimal settings for HWEC related parameters in wanpipe1.conf to be able to receive Fax over T.30 on a Sangoma A108DE Card ? In particular, should I enable echo ? If yes, to what parameter ? What other values like RXGAIN, TXGAIN should I tune ? TDMV_HW_DTMF = YES # YES: receive dtmf events from hardware TDMV_HW_FAX_DETECT = YES # YES: receive fax 1100hz events from hardware HWEC_OPERATION_MODE = OCT_NORMAL# OCT_NORMAL: echo cancelation enabled with nlp (default) # OCT_SPEECH: improves software tone detection by disabling NLP (echo possible) # OCT_NO_ECHO:disables echo cancelation but allows VQE/tone functions. HWEC_DTMF_REMOVAL = NO# NO: default YES: remove dtmf out of incoming media (must have hwdtmf enabled) HWEC_NOISE_REDUCTION = NO# NO: default YES: reduces noise on the line - could break fax HWEC_ACUSTIC_ECHO = NO# NO: default YES: enables acustic echo cancelation HWEC_NLP_DISABLE= NO# NO: default YES: guarantees software tone detection (possible echo) HWEC_TX_AUTO_GAIN = 0 # 0: disable -40-0: default tx audio level to be maintained (-20 default) HWEC_RX_AUTO_GAIN = 0 # 0: disable -40-0: default tx audio level to be maintained (-20 default) HWEC_TX_GAIN= 0 # 0: disable -24-24: db values to be applied to tx signal HWEC_RX_GAIN= 0 # 0: disable -24-24: db values to be applied to tx signal regards, Anita -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] ph_tor3_e1.c
We are running FreeTDM on a very cheap Atcom card, which used another module ph_tor3_e1 on top of Dahdi. I believe this is derived from Torrenta. http://www.atcom.cn/downloads/TelephonyCard/drivers/AX-4ET/E1/ph_tor3_e1.c On Ubuntu 10.04 this gives problem as the module ph_tor3_e1 (and hence dahdi) does not unload. Sometimes the machine hangs and needs to be rebooted. This module has not been updated for the last 2 years during which the linux kernel has changed (I am told). Is there any other manufacturer of torrent card who would be using the same architecture and keeping his drivers updated ? If not, what steps do I need to take to update this driver to kernel version 2.6.32-37-server ? These are new waters and I feel so helpless :) regards, Anita regards, Anita -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] Video IVR Asterisk ?
Hi Is it possible to receive video calls using Asterisk and then process them as an IVR ? One of our clients wants to set-up a video IVR system in the US and we are evaluation possible options. Also, what is the bandwidth of receiving a video call in US ? What protocols and codecs are supported and does it work on DID numbers ? Can I rent a hosted solution for this ?

[asterisk-users] E3 Card on Asterisk ?
Hi Please check out this product http://www.sangoma.com/products/hardware_products/data_networking/a301.html Does it work on Asterisk or Freeswitch ? Do Telcos provide an E3 connection ? One of our customers had an inquiry for terminating 6000 calls simultaneously. I want to do some homework before taking it further with him. If I use E1 lines, I will need 6000 / 30 = 200 E1 lines, which does not look feasible ?
