Weve got cisco 2811 4 FX0 (cisco R) from the one hand and cisco 2811(cisco N) from the other.
On the cisco R is ios 12.3(11) T3+ Call Manager Express 3.2. To that cme connected 7960 and also cisco 7940
To cisco N connected Avaya through FXO
connection scheme is following:
ipphones switch - eth 0/0.2 Cisco R serial 0/2/0 -- WAN -- serial 0/2/0 Cisco N -- Avaya
On the cisco R, inside cme everything works ( call, transfer, hold and so on) the call goes to Avays. You can talk, but the problem appears when subscriber cisco R put hold of the subscriber cisco N. After switching back from hold appear one side signal ( cisco R can hear, cisco N cant)
The following situation appears:
- The call goes from cisco N(ext 3301) to IPPhone CISCO (ext 3519), no matter what is the direction of the call, there is one and the same problem all the time.
- 3519 picks up the receiver
- the conversation keeps going but when appears the necessity from the 3519 to switch 3301 to the hold , he (3519) presses hold batten
- 3301 is on the hold session ( no matter how much time that takes), 3301 hear just silence ( in spite of the fact that there must be moh file option)
- 3519 comes back from hold session, hears what 3301 says, but 3301 doesnt hear 3519
- If transfer call from the hanging hold call to the other number, to 3525, f.e. the hearing will be normal, but if press hold again, the same problem appears.
I would like to underline that cme works fine, if press hold for the incoming call from 3525 to 3519, the 3525 will hear beep signal (as it should be), if press hold for any call from FXO, FXO will hear music.
Sh config for cisco R and cisco N are in the attached file
There is no problem with hold function for the cisco N
Nevertheless, curious to relate, but there is no problem before press hold, inside CME the problem with hold doesnt exist at all! I would open tac with pleasure, but the problem is I cant understand what criteria I should use for searching tac, for that purpose I wrought complete config of both rooters. If you have any idea concerning that question, please let me know.
