Today i am doing a POC to test R2 interoperability between Cisco 2801 (VWIC-2MFT-E1-DI + VIC2-2FXS + CP-7940) with Lucent Definity G3 PBX. I used and followed config guide from http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis3600/sw_conf/pbx_int/36lde1r2.pdf
The results are:
1. Voice call from Cisco to Avaya is working, but Cisco's ANI is not shown on Lucent Phone instead it shows Avaya TAC number & trunk name.
2. Voice call from Avaya to Cisco is also working and Avaya's ANI is shown on Cisco IP Phone.
The issue is Avaya's ANI is not shown on Cisco IP Phone.
We asked Avaya's engineer to make a change on Multifrequency-Signaling-Related System Parameters -> request incoming ANI (non-AAR/ASR) to 'y' (Cisco config guide set 'n'). For detailed change see attachment
After tested call from Cisco to AVAYA, call setup took about 10 seconds to connect (before, it only takes less than 3 seconds) however Cisco' ANI is now appear on Lucent Phone.
I used debug to capture the message between them. Here the log.
Apr 22 20:48:16.866: R2 Outgoing Voice(0/0): DSX (E1 0/1/0:28): STATE: R2_OUT_PROCESS_A R2 Got Event R2_TONE_OFF
Apr 22 20:48:16.866: r2_reg_generate_digits(0/1/0:1(29)): Tx digit 'B'
Apr 22 20:48:25.018: htsp_dialing_done(0/1/0:1(29))
Apr 22 20:48:27.398: htsp_digit_ready_up(0/1/0:1(29)): Rx digit='3'
Apr 22 20:48:27.398: R2 Outgoing Voice(0/0): DSX (E1 0/1/0:28): STATE: R2_OUT_PROCESS_A R2 Got Event 3
From message above, on time stamp Apr 22 20:48:16.866, Cisco sends Tx digit 'B' to Avaya, but avaya sends response Rx digit='3' around 10 seconds later.
My questions are:
1. What is Tx digit 'B'? why Cisco sends alphabet as digit instead of numeric? i guess Avaya doesn't understand this. That's why it takes 10 seconds to make respond.
2. Can we modify Tx digit 'B' setting? if not is there ways how to speed up call setup?
Anybody has ever had this issue? Appreciated if somebody could help.
