Hi all!


Im have this case:

PSTN -> (e1) -> router1 -> WAN -> router2 -> e1 -> PSTN


im using this for cost purpose, i redirect a fax call to a "external voice-mail fax".

I tried to create a dial-peer voip gateway to gateway but didnt work.


lets me show the config of router1.



!

voice class codec 2

codec preference 1 g711ulaw

!

!

!

voice class h323 1

h225 timeout tcp establish 5

!

!

voice translation-rule 6925

rule 1 /^6925/ /028452546/

!

!

voice translation-profile FAX-CT

translate called 6925

!

dial-peer voice 69251 voip

translation-profile outgoing FAX-CT

destination-pattern 6925

voice-class codec 2

voice-class h323 1

session target ipv4:10.111.8.7

dtmf-relay h245-alphanumeric

!


Ip of router2 is 10.111.8.7


When i call to 6925, i hear the fax ringback ( because 028452546 answer the call ) but error occurs.

I see the call (on #show call active voice brief) that does on g711ulaw

Add this to your configuration:


voice service voip

modem passthrough nse codec g711ulaw



I think this will help.
