It sounds like Bell is waiting for more digits. Sending a # after sending the number may resolve this issue. Bill
Bill Paris Network Engineer Delaware North Companies 40 Fountain Plaza Buffalo NY 14202 (716) 858-5312 >>> Abebe Amare <[email protected]> 10/14/2014 10:21 AM >>> Hi, I am having a hard time convincing the local telco that outgoing calls to PSTN numbers take about 11 seconds before the voice router receives CALL_PROC from their switch. They insist this is normal and want to dismiss the case but the delay is noticeable. Incoming calls have no problem. The PRI line comes using microwave media due to lack of copper last mile to the site and it connects to Cisco 2901 voice router which connects to CUCM using SIP. I have sent them the output of 'debug isdn q931' as follows: *Oct 11 11:48:12.999: ISDN Se0/2/0:15 Q931: Applying typeplan for sw-type 0x12 is 0x2 0x1, Calling num xxxxxxxxx *Oct 11 11:48:12.999: ISDN Se0/2/0:15 Q931: Sending SETUP callref = 0x00C2 callID = 0x8043 switch = primary-net5 interface = User *Oct 11 11:48:13.003: ISDN Se0/2/0:15 Q931: TX -> SETUP pd = 8 callref = 0x00C2 Bearer Capability i = 0x8090A3 Standard = CCITT Transfer Capability = Speech Transfer Mode = Circuit Transfer Rate = 64 kbit/s Channel ID i = 0xA9839F Exclusive, Channel 31 Calling Party Number i = 0x2180, 'xxxxxxxxx' Plan:ISDN, Type:National Called Party Number i = 0x81, 'yyyyyyyyy Plan:ISDN, Type:Unknown *Oct 11 11:48:13.295: ISDN Se0/2/0:15 Q931: RX <- SETUP_ACK pd = 8 callref = 0x80C2 Channel ID i = 0xA9839F Exclusive, Channel 31 *Oct 11 11:48:24.167: ISDN Se0/2/0:15 Q931: RX <- CALL_PROC pd = 8 callref = 0x80C2 *Oct 11 11:48:31.127: ISDN Se0/2/0:15 Q931: RX <- ALERTING pd = 8 callref = 0x80C2 Progress Ind i = 0x8488 - In-band info or appropriate now available *Oct 11 11:48:39.975: ISDN Se0/2/0:15 Q931: RX <- CONNECT pd = 8 callref = 0x80C2 Connected Number i = '!', 0x83, 'yyyyyyyyy' *Oct 11 11:48:39.975: ISDN Se0/2/0:15 Q931: TX -> CONNECT_ACK pd = 8 callref = 0x00C2 *Oct 11 11:49:06.119: ISDN Se0/2/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x00C2 Cause i = 0x8090 - Normal call clearing *Oct 11 11:49:06.423: ISDN Se0/2/0:15 Q931: RX <- RELEASE pd = 8 callref = 0x80C2 *Oct 11 11:49:06.423: ISDN Se0/2/0:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x00C2 Is there anything I can do from my side to lower this delay? best regards, Abebe The information contained in this electronic mail transmission is intended only for the use of the recipient(s) named above.
