Trouble with modems link

Hi all !

I have got what looks like a hardware trouble to connect 2 Cisco routers
1601) by modem.
Modems are US-Robotics Courrier, one "V32 bis Fax with ASL", one "V
Everything" with X2 56K technology, both in auto-answer.
I use a POTS PBX to link both routers.
I use all proper cables, Serial DB-60 to RS-232 DTE, but only the "V32
bis Fax with ASL"connects succesfully. All looks as if with the "V
Everything" modem no number towards destination was composed at all, PBX
shows properly "270" trying to call "260" when "V32 bis Fax with ASL"
makes the call, but in the other way when the "V Everything" makes the
call PBX shows "260" trying to call "", no destination number is shown.
Of course I tried to simply swap the modems to check whether problem
comes from modem or routers, and it worked, so it looks like a bad
hardware config on "V Everything" modem.

Has anyone experienced such a trouble ?

Config for SanJose1 with "V32 bis Fax with ASL" on it is :

hostname sanjose1
!
username sanjose2 password 0 cisco
!
interface Serial0
physical-layer async
ip address 192.168.8.1 255.255.255.0
